Chapter 276: Calculation Methodological Problems
After a series of mechanical equipment, reference prototypes and technical data for the production of military electronics industry have been put in place, various follow-up work has also been carried out, from the transformation of the plant to the installation and commissioning of mechanical equipment; from the study of the reference prototype to the collation of various technical data; from the innovation of production technology to the training and education of personnel, the work is interlocking, mutual promotion and overlap are very high.
In the face of such complicated work, the leaders of the Central Plains Electronic Radar Institute at all levels, including Zhong Xiaomo, have encountered such a complicated situation, and what to focus on, what to give priority to solving, and how to promote coordinated development.
When these practical problems are placed in front of Zhong Xiaomo and other leaders of the institute, their heads are all a mess, in fact, this is not surprising, after all, the leaders of the institute are basically engaged in technology, and when it comes to technical level, it can be said that they are outstanding.
But they all lack a wealth of management knowledge and experience, because of this, when they see so many advanced equipment and technical data, they are as happy as the dream baby, but in the face of such a complex system work, Zhong Xiaomo and others are more headaches than encountering extremely difficult to solve parameter equations.
This is like a Sven person in front of a delicious and huge piece of meat, with chopsticks can not be clamped, with a knife and afraid of delaying time, directly with the hand is insulting Sven, in this way, it will end up in front of the gluttonous food, but nowhere to put the mouth of the embarrassing situation, fortunately, Lu Jiadong foresaw this early, because Lu Jiadong is very clear that in this era in addition to the relevant technology is weak, the overall management model also has great limitations.
After all, as a military expert who came from later generations, Lu Jiadong has been deeply involved in much more complex projects such as anti-ship ballistic missiles and domestic aircraft carriers, so he is familiar with how to efficiently promote and carry out the current artillery reconnaissance and school firing radar, and because of this, Lu Jiadong has made a series of targeted adjustments and promotion measures:
In the general direction. To this end, Lu Jiadong divided the entire research and development team into several sub-project teams, such as theoretical calculation, computer improvement, and system integration, and formulated the specific requirements and development directions of each sub-project according to the overall requirements. In order to speed up the development of radars.
For example, Song Xiaoxu, who has outstanding talent in the computer field, was entrusted by Lu Jiadong with the important task of researching and imitating the American-made AN\UYK-16 military small computer. Either as the leader of the sub-project, or as the core of the technology to play an important role in the development of radar, so that the capable people can play the greatest role in their rightful position.
In terms of product manufacturing, Lu Jiadong actively promotes the transformation of dust-free workshops, in order to speed up the progress of Lu Jiadong through Liu Haotian's coordination and the support of the superior departments, specially transferred a railway engineering regiment to participate in the transformation of the plant, at the same time, for such a batch of new machines, new equipment to vigorously carry out the education and training of professional and technical personnel, in order to achieve the construction of the plant and production capacity at the same time!
However, doubts about Lu Jiadong's taking such measures have also occurred from time to time, and this situation has been encountered every time. Zhong Xiaomo, as the director of the Central Plains Electronic Radar Institute, stood firmly on Lu Jiadong's side, in addition to Liu Haotian, Tan Bin, Qian Lei and other major leaders of the military industry have given strong support to Lu Jiadong, so even if there are some doubts, they can't make too much trouble, so this set of measures is relatively smooth in the implementation process.
In this way, through the concerted efforts of Lu Jiadong and all the scientific research personnel of the Zhongyuan Electronic Radar Institute, the entire artillery radar development and other supporting projects were able to move forward efficiently and rapidly, and the renovation project of the dust-free workshop was completed in just one month.
For example, in the field of computers, thanks to the support of the AN\UYK-16 military small computer and its detailed technical data, Song Xiaoxu quickly figured out the principle. Relying on the new military electronics production workshop, which had already formed its initial manufacturing capacity, the improved DJP-140 small computer was soon developed, which not only reduced its size by more than half, but also greatly reduced its weight. The trouble-free time has been increased to more than 2,000 hours, and the overall performance has basically reached or even surpassed the performance of the AN\UYK-16 military small computer.
Of course, military small computers are only one of many breakthrough achievements, such as new ASIC circuits, complete automatic detection systems, high-power transmitters, high-precision receivers, and integrated circuits on the process of one-time molding, plasma treatment, etc., in a word, that is, the achievements are like a hundred flowers blooming, brilliant and colorful. Colorful!
It is precisely under the nourishment of these splendid and beautiful flowers that the greatest foundation, which is the artillery radar, will become more and more solid and stronger, so that the high mobility, high precision, fast reaction time, and convenient maintenance of the entire radar will have a qualitative leap, and a prototype of a new artillery radar will soon be manufactured.
For this artillery radar, which has applied many high and new technologies, many personnel involved in the development have great confidence, and you must know that the technology used in this radar is one of the best in the world, coupled with the hard work and dedication of many scientific research personnel, even if there are flaws, it can definitely be described as extraordinary in terms of basic performance.
However, what everyone didn't expect was that this radar, which gathered the hopes of countless people, had poor signal processing ability, blurred image display, weak anti-jamming ability and other shortcomings during the first test flight, such a performance was tantamount to a basin of cold water poured on everyone's body from head to toe in winter, so that everyone was instantly sober, radar this high-tech weapon and equipment did not solve the hardware problem, all other difficulties were solved, and it is a long way to go to achieve the ideal performance!
"The fundamental reason for the situation with the new artillery radar is that we have problems with the calculation of the relevant signal processing!"
In the evening, in the theoretical laboratory of the Central Plains Electronic Radar Institute, Lu Jiadong, Song Xiaoxu and others sat around the small conference table on one side, listening carefully to Zhong Xiaomo, the chief designer of the artillery radar, on the analysis of the reasons for the failure of the artillery radar. He held a thick stack of theoretical calculations in his hand, his small but godly eyes were covered with thin bloodshots, and his voice was a little hoarse:
"Speaking of which, there is a deviation in the specific calculation theory we apply. Although the traditional calculation method saves time, there are huge defects in signal processing, data compression, image display anti-interference ability, the equipment we applied in the past is relatively backward, and the application of this calculation method is nothing, but now we have integrated a large number of advanced equipment and high technology. The limitations of this traditional calculation method are extremely prominent, so we must improve on the basic basis of the calculation method!"
"Director Zhong, finding a new calculation method is easier said than done! But it is much more difficult to do it than to introduce advanced machinery and equipment!" As soon as Zhong Xiaomo finished speaking, an old researcher sitting not far from him who was in charge of the overall system integration of artillery radar frowned and said:
"What's more, even if we have some vague ideas and directions, it takes a lot of time to calculate, demonstrate, and apply to radar this kind of calculation, as little as a year, more than several years, or even decades, do we have so much time and experience to invest in this area!"
The old researcher was right. A new calculation method is tantamount to a great innovation and invention in the field of mathematics, such mathematical innovations in human history can be said to be numerous, but each time it has gone through a long process, sometimes it is just a short-lived conjecture, such as the Gottbach conjecture, which has taken hundreds of years of human time and has not calculated the truth contained in it, which shows that the difficulty is beyond the imagination of ordinary people.
The research of new algorithms is even more so, just like finding an embroidery needle in the vast digital ocean, which requires superb theoretical foundation, rich research experience, tenacious willpower, sudden inspiration, unparalleled luck and many other controllable and uncontrollable factors superimposed at one time to achieve this goal.
The people present are all veteran technicians who have been fighting in the field of electronic radar for many years. Having worked with numbers and formulas for many years, they knew exactly how difficult it was, and because of that, the old researcher said that. Several people present nodded in agreement, and one of the old technicians who was very familiar with Zhong Xiaomo asked Zhong Xiaomo bluntly:
"Director Zhong, is there no other way than to create a new calculation method?"
The old technician's question can be said to have asked everyone's voice, so the eyes of everyone present focused on Zhong Xiaomo's body, and even Lu Jiadong, who was sitting opposite him, couldn't help but raise his head. He looked straight at the chief designer of the artillery radar.
And Zhong Xiaomo faced the expectant, puzzled, or puzzled eyes of everyone present, and wanted to say it according to everyone's wishes, but after all, he was the chief designer of the artillery radar, and his scientific rigor and truth-seeking made him unable to go against his heart, so even if he couldn't bear it in his heart, he still shook his head helplessly, although his bloodshot eyes showed a trace of reluctance, but he still said truthfully:
"I have done a lot of arguments, we have no problems in all aspects of the radar, what is lacking is the basic calculation method, it can be said that this most basic problem is not solved, even if we produce more advanced supporting equipment, no matter how to adjust the mechanism structure, it is useless, because the core problem cannot be solved!"
Listening to Zhong Xiaomo's words, everyone present lowered their heads and chose to be silent, because everyone knows that Zhong Xiaomo has always been a very rigorous person in terms of technology, and Lu Jiadong, who is sitting opposite him, is also very clear about this, since the development of the new artillery radar undertaken by the Central Plains Electronic Radar began, Zhong Xiaomo has devoted himself to the development of artillery radar.
Especially after the failure of the artillery radar test, Zhong Xiaomo personally went into battle to conduct a comprehensive inspection of the radar in order to find the cause of the failure, but it is not easy to find the cause of the failure in such a complex weapon and equipment, you must know that the artillery radar contains many disciplines,
An inconspicuous reality system alone contains more than 10 categories and disciplines such as electronics, basic physics, classical mathematics, materials science, etc., and the entire radar system is even more all-encompassing, and its complexity is far more than that of ordinary weapons and equipment, and the reason for the failure may lie in any of these nodes, because of this, finding the reason is similar to looking for a needle in a haystack!
But even so, Zhong Xiaomo still put his mind into finding one system at a time, exploring one component at a time, and the entire test-installed radar was dismantled and installed by him, installed and dismantled, just like that, it was repeated more than a dozen times, and the scratch paper for argumentation and calculation was even more innumerable, and the whole person was like a never-ending spinning top, and began to rotate wildly, but the artillery radar involves a wide range of disciplines.
In order to speed up the search progress, Zhong Xiaomo specially applied to the Commission of Science, Technology and Industry for National Defense to use the latest DIS-2400 large-scale computer in the computer center of Tsinghua University in Beijing to carry out theoretical data deduction and calculation.
Because even after the calculation of the large-scale computer is completed, Zhong Xiaomo still has to take the calculation results to conduct a complex and cumbersome data comparison, and in this comparison, he found that several experimental values and theoretical values have a large deviation, after careful research, Zhong Xiaomo found that this may be related to the basic calculation method of radar, it is because of many careful and meticulous inquiries and calculations, Zhong Xiaomo will say this conclusion here.
So when Zhong Xiaomo finished saying this, the entire laboratory was suddenly silent, because everyone knew that Zhong Xiaomo's conclusion had a solid basis for argumentation, and no one knew how to solve this big problem, so they had no choice but to be silent (to be continued). )
