The battlefield is always the first place where the latest technology is applied, and countless elites in the world are studying how to kill humans better and faster all the time. Pen "Fun" Pavilion www.biquge.info

Artillery is an important part of the army and the main fire assault force, with powerful firepower, long range, good accuracy, and high mobility capability, and can carry out fire assaults on ground and surface targets in a concentrated, sudden, and continuous manner.

Artillery is mainly used to support and cover the combat operations of infantry and armored troops, and to cooperate with other arms and services, and can also be used for firepower combat. Therefore, artillery has the title of "god of war" in history.

Since the 90s of the 20th century, artillery has become the largest branch of the Chinese army. In the face of modern warfare, the strike capability of our army's artillery has also made a qualitative leap.

Among them, the tools that play an important role in it are various types of artillery reconnaissance and positioning radars.

The Air Force Radar Research Institute is currently working on the BL-904 ground artillery position reconnaissance radar, which is an artillery positioning radar using phased array radar technology, which is mainly used to reconnoiter mortars, howitzers, rocket artillery and howitzers on the battlefield.

Through continuous improvement and research, the performance of the BL-904's gun position detection radar has been greatly improved, its reaction time has been shortened to 5 seconds, and it can calibrate its own artillery fire. In addition, its deployment time, elevation coverage, azimuth coverage, and target distance positioning accuracy are constantly improving and improving.

In order to enable the artillery to grasp the operation of this reconnaissance radar more conveniently, quickly, and accurately, the departments concerned have once again put forward a demand for the radar research institute, requiring the control system to keep pace with the times and upgrade the previous character terminal interface to a graphical operation interface. Simplify the operation process of artillery, so that ordinary artillerymen who do not have professional higher education can also operate conveniently. to adapt to the ever-changing battlefield situation.

Originally, this task was not the turn of the Air Force Radar Research Institute, after all, their subordinate unit was empty, and it was not their turn to do artillery things.

But who made them do the best in this area?

In the whole system, their research institute is famous for its control system, and the system they made was welcomed by the majority of soldiers, and they all thought that they had made it. Visual, intuitive and easy to operate, even soldiers who have not gone to school, after simple training, can operate one or two.

And they are also leaders in phased array radar technology. Isn't Professor Xu Zhizhong the director of their institute? Make this thing. It's the most suitable.

So, back and forth, the project was parachuted into their research institute.

As Dai Xingping said. The system they use is a secondary development on the Windows system, and this system is a closed-source system, and all they can get is the SDK announced by Microsoft.

They don't know the details and write the program entirely at the application layer. The underlying details have been encapsulated by Microsoft, albeit after so much research. Their technicians have also detected a lot of the underlying stuff through special means, but it is simply impossible to figure out all the details.

As a result, when they write programs, they sometimes accidentally encounter some strange bugs, such as accidentally covering the memory area of the system, or a driver is incompatible with the system, resulting in frequent blue screens, and then like this one, often inexplicably and suddenly the software crashes...... Wait a minute.

In order to be able to make the system run more stably, they had to spend a lot of extra time solving these problems, and even more time they spent on these problems than they did on programming control programs.

Every time the control program is made, they have to constantly test, all kinds of limit tests, long-term running, all kinds of tossing, in order to ensure that when the user uses it, there will be no sudden blue screen or flashback.

You must know that if there is a sudden crash or blue screen at a critical moment on the battlefield, it is very likely that the timing of the counterattack will be measured, and it is even related to the victory of a war.

The system, itself has a lot of bugs, and there are a lot of bugs, and under their continuous optimization and patching, it has become a workable system, at least for those products developed on this framework, the feedback from the majority of users is still quite good, even if there are occasional bugs, it is also within the acceptable range.

However, is this really the case?

Can a general-purpose system that is not real-time really be able to withstand the test of such a harsh environment on the battlefield?

Lin Hong naturally disagrees with this.

As soon as he heard about the system they were using, it turned out to be safer and more stable.

The debriefing from the technician who came in interrupted their conversation.

They don't have much time left for testing and debugging this project, and tomorrow is the last day, and it will be delivered immediately.

Dai Xingping said something, and then went to the R&D room with his nephew Yu Bo and the technician.

"Grandpa Xu, what project are they doing now?" Lin Hong asked with some curiosity.

"The BL-904 control system is upgraded, a domestic system for the detection of the artillery position radar." Xu Zhizhong didn't hide it, and said it directly.

The name of this radar is not a secret, because China had already put it into use during the Vietnam War, and it played a very important role at the beginning, and it was also known to the outside world for the first time, and later the Western media did a more extensive investigation and report on this matter.

"BL-904......" Lin Hong nodded knowingly when he heard this.

Xu Zhizhong saw that he seemed to know, and couldn't help but be curious: "You also know something about this?" ”

"I have learned about some, but these materials are all learned from foreign media or some other institutions, which may be a little inaccurate."

Hearing Lin Hong say this, Xu Zhizhong became more interested, he knew that Lin Hong had been abroad before, and the way to get this information could naturally only be a foreign agency, he asked:

"Tell me about the data you've learned."

"BL-904, produced by NORINCO, is an artillery positioning radar with phased array radar technology, operating in the C-band, loaded by two 6-wheeled trucks, one of which is equipped with an antenna and a receiving transmitting unit, and the other with an operating compartment...... Its deployment time is less than 10 minutes, the elevation coverage is +12°~-5°, the azimuth coverage is +/-90°, and the target distance positioning accuracy is 35 meters to 3.5% of its target range......."

Memorizing data, this is Lin Hong's strength, he searched for the corresponding information in his mind, and it came as soon as he opened his mouth, and it was completely a professional term, basically the same as the information he saw.

And Xu Zhizhong's face became more and more surprised with his words, and by the end he was already quite shocked.

“…… The positioning distance is 15 km against 82-mm mortars, 25 km against 122-mm howitzers or 18 km for rockets, and 18 km against 155-mm plus howitzers; Able to deal with 8 targets at the same time; The automatic north finder and GPS autonomous positioning and orientation are adopted, and the target data is transmitted to the command post through wired and wireless communication devices. Its performance has been comparable to the American TPQ-36 mortar targeting radar, and in some respects even surpassed it. ”

Hearing the end, Xu Zhizhong's face was already quite serious, and it could even be said that it was Tie Qing.

"Where did you get this data from?" Xu Zhizhong asked with an unusually serious expression.

The data that Lin Hong is talking about are not the public data that the Western media often resort to in the newspapers, but the latest upgrade data of this kind of artillery position reconnaissance radar.

In fact, their upgrade this time is not only a graphical improvement, but also adds a lot of functions, and it is a fundamental change in the way some data is processed, so that on the basis of not changing the hardware structure of the entire artillery system, only through software upgrades, its performance has been improved a lot.

And the problem is that here, these parameters reported by Lin Hong are simply just data that are still stuck in their research institute, that is, data that even domestic artillery does not know, but Lin Hong knows it in advance.

What does this mean?

This means that the data is leaking directly from them!

Xu Zhizhong had to pay attention to this situation, and all kinds of thoughts were circling in his mind, the most important of which was that there was a very good chance that someone in the institute would leak secrets, but he didn't know whether it was an unintentional leak or an active leak, no matter what the situation, it was worth his great attention as a director.

Lin Hong also looked at Xu Zhizhong with some surprise, he didn't expect the other party to be so shocked and attached importance to his words.

He obtained these data only last night, so that he could have a more overall understanding of their Air Force radar research institute.

He wants to know the intelligence here, and he wants to get it by hacking into the domestic network, which is relatively much more convenient than hacking foreign intelligence agencies.

As the saying goes, "it is difficult for a good woman to cook without rice", Lin Hongkong has a skill, but in the face of such a backward network environment in China, the vast majority of institutions and departments do not even have access to the Internet, how can they obtain this information?

In this respect, there is a benefit to not having an Internet, and at least to get information, you have to start on the ground or get it through the hands of secret agents.

He didn't realize what the data he was talking about before, and it took him half a day to come back to his senses from Xu Zhizhong's reaction, feeling that the data he reported was the latest achievement in them. (To be continued)
