Hearing Lu Jiadong's words, Song Xiaoxu on the other end of the phone couldn't help but be slightly stunned, and then rubbed his eyes, which were a little red because of staying up late, and said sneeringly:

"Old-fashioned 515-meter wave radar?"

"That's right, it's the old-fashioned 515-meter wave radar!" Lu Jiadong's voice was confident and firm, and then continued in an accentuated tone:

"Of course, there are many derivative models of this radar, but I think the most suitable for improvement now is the 515B meter-wave radar equipped on the brigade-class destroyer, after all, the land-based model of the 515 meter-wave radar is only a two-coordinate radar, the detection distance of the target is no problem, but the detection accuracy is not flattering, and the combat use must be assisted by the altimetry radar to achieve three-coordinate positioning;

In this way, the structure of the radar group is too large, which is not conducive to maneuvering, not to mention that the signal beam of the altimetry radar is not the same as that of the meter-wave radar, and it cannot realize continuous wave conversion, neither can detect the stealth fighter, nor has the ability to evade the attack of the anti-radiation missile;

In this regard, the 515 type B equipped with the brigade class has been overcome, after all, the space on the ship is small, it is impossible to integrate the altimetry radar together, and the meter wave radar itself can only be used to monitor and detect long-range targets, so this radar has been improved at the beginning of the ship, although it has not fully realized the three-coordinate detection capability, but it is much easier to improve.........."

Lu Jiadong held the phone in his hand and talked eloquently, which can be described as a treasure of the 515 radar, but what others don't know is that in fact, Lu Jiadong is not familiar with the 515 radar, and the reason why he can tell the story of the 515 radar is because he is very clear about the birth of another model of meter-wave radar, that is, it will become the main ship standard equipment in later generations H/LJQ-517 anti-aircraft warning mine, that is, the famous 517-meter wave radar!

Speaking of the 517-meter wave radar, its origin can be traced back to the 515-meter wave radar equipped with the brigade class, when the brigade class missile destroyer was built, there was an important combat mission, that is, the brigade destroyer undertook the air defense radar alert ship, and cooperated with the air defense forces on land.

The air defense early warning range was extended to the sea for hundreds of kilometers, but at that time, China's military electronic level was very backward, coupled with the lack of understanding and experience in the use of shipborne radar systems, resulting in no high-performance shipborne radar for its equipping, and in a hurry, the development personnel at that time could only rigidly modify the land-based 515-meter wave long-range warning radar and install it on the brigade-class destroyer.

This expedient measure, although it solves the task needs of the brigade class to undertake the task of air defense alert ships, but the disadvantages of water and soil adaptation can never be solved, after all, the land environment and the marine environment are very different, especially the harsh climate and humid salt spray at sea, which has a huge corrosive effect on electronic equipment.

In addition, the 515 radar itself has poor anti-jamming ability, slow response speed, low detection accuracy and other shortcomings, so when the Chinese Navy obtains a more advanced shipborne radar system, it will not hesitate to eliminate all the 515 meter wave radar, which can be seen from the radar system equipped with many 051 improved models and 052 type missile destroyers in the nineties.

Logically speaking, the 515-meter-wave radar is completely submerged in the dust of history under the impact of the new generation of air defense radar, but the so-called unpredictable world, just when the 515-meter-wave radar is ready to become ancient, China's anti-stealth technology has made a breakthrough, in addition to the use of atmospheric electromagnetic wave disturbance to locate stealth fighters, another practical method is to use the meter-wave radar to carry out detection and positioning.........

The Chinese Navy is not only an air defense position extending on land, but also has to carry out independent air defense combat missions in the far sea, and it is precisely because of this that how to counter the threat of stealth fighters has also become a research topic for the Chinese Navy, and when it was learned that the meter-wave radar can detect stealth fighters, naval equipment experts immediately thought of the 515-meter wave radar equipped on the brigade level.

Although this radar has many shortcomings, but after so many years of equipment and improvement, the overall adaptability and maturity is incomparable to other radars, as long as the use of modern electronic technology is slightly improved, it can become a sharp weapon to strip off the coat of stealth fighters, so a 515-meter wave radar based on the improvement and upgrading of the 517-meter wave radar was born........

Even if it is equipped with a phased array radar, known as the "China Aegis" Type 052C missile destroyer, a few years later the more advanced 052D also appeared on the 517-meter wave radar, so far this radar has become the standard equipment of the Chinese Navy, and its successful counterattack by the almost eliminated old-fashioned equipment has also become a good story talked about by the military industrial system, Lu Jiadong, as a military expert who came from later generations, although he did not personally participate in the development of the 517 radar, but this good story is familiar.

The reason why it was not proposed before is mainly because Lu Jiadong is also a perfect person in his bones, although the 517 radar is feasible, but the detection ability of stealth fighters is not perfect, and it cannot be compared with the professional anti-stealth radar of the phased array system, so if the phased array system radar can be developed, Lu Jiadong naturally wants to do it in one step.

It's just that the time is a little tight at the moment, if you can't catch up with the Iraqi bidding, all of them will be in vain, and because of this, when he received Song Xiaoxu's somewhat pessimistic feasibility report, Lu Jiadong could only retreat to the second, first solve the problem, and then take the road of refinement and improvement, so he proposed the 517 radar plan..........

"As for the focus of improvement, I think it is still on improving the specific performance of the radar, such as detection accuracy, strengthening anti-jamming capabilities, improving data processing capabilities, of course, interference analysis adaptive frequency agility ability is also indispensable, after all, the current anti-radiation missile is an important threat that cannot be ignored, as for the radar system, I don't want to change, as long as it can be integrated into the truck..........

After listening to Lu Jiadong's narration, Song Xiaoxu was a little surprised at first, but then there was a burst of ecstasy, and the hand holding the microphone trembled slightly, so that even the tone changed a little:

"The 515 radar is used to improve and enhance the accuracy........ Added adaptive frequency agility function....... Improve data processing capabilities........ 515 Radar ....... 515 radar, such a good foundation, how did I not think of it, how did I not think of it....... My brain ........"

After a burst of excitement, Song Xiaoxu couldn't stop blaming himself, and his frustrated tone was accompanied by the sound of "pop~~pop~~~" with his palm slapping his head and passed into Lu Jiadong's ears along the phone line, making Lu Jiadong smile and persuade softly:

"Why pat your head? Don't blame it too much, you must know that it's not that it can't think of it, but that you make it too tired and groggy all day, how can you think of it?"

Lu Jiadong is right, in fact, it's not that Song Xiaoxu can't think of it, you must know that the development unit of the 515 radar is the Central Plains Electronic Radar Institute back then, Song Xiaoxu can't be unfamiliar with this, but he is bent on thinking about a more advanced phased array system, and ignoring other methods, plus the rest is not good, some authorities are confused, as long as a little reminder, it will naturally be able to understand it, but Lu Jiadong can see it, but Song Xiaoxu doesn't think so:

"Mr. Lu, don't lift me up, I still have to overcome the old problem of riding a donkey to find a donkey, to be honest, if you don't keep mentioning it, the anti-stealth radar won't be able to get to now, to be honest, if there is no Mr. Lu, there will be no anti-stealth radar!"

"Okay, okay, don't put a high hat on me anymore, I'm just a paper talker at best, let me say yes, if you really want me to do it, I really won't know anything, so the real hero is still Xiaoxu yours!"

Lu Jiadong said it from the heart, although he is familiar with the field of military electronics such as radar, but it is limited to this, if he is allowed to do something, it is really a bit of a duck to put on the shelf, the reason why he can explain the relevant principles is the truth, but it is just to occupy the identity of the traverser,

It's just a matter of talking about the basic principles of equipment that have long been matured, and as for its real realization, it still depends on military technicians like Song Xiaoxu who have solid technology and a rigorous attitude, but Lu Jiadong's heartfelt words fell on Song Xiaoxu's ears but they were another refreshing encouragement:

"Mr. Lu, you are really ......... Your kindness, I Song Xiaoxu remember it in my heart, I am a military electronics, and I will not say anything, but I will tell you with practical actions, Mr. Lu, you are not wrong!"

Hearing this, Lu Jiadong paused for a moment, and even after reacting, Song Xiaoxu would be wrong, and wanted to explain immediately, but as soon as the words came to his mouth, he stopped him, just smiled helplessly, and then said:

"I'm sure you'll be the best in your field!"

"Don't worry, Mr. Lu, I will never live up to your expectations........."

In this way, the two of them talked for a while, and after further finalizing some details of the improvement of the 515-meter wave radar, Lu Jiadong put down the phone, and at this time, the door was suddenly knocked gently, Lu Jiadong immediately opened the door, and saw the secretary standing at the door with a stack of documents, which made Lu Jiadong a little puzzled, and hurriedly asked:

"......... you are"

"Mr. Lu, this is the test data of the missile test launch you wanted, and the test site has just been sorted out!"

Looking at the information in the secretary's hand, Lu Jiadong remembered that he didn't even go to the Shencheng Factory when he came back from abroad, and came here directly, just for the test launch of the anti-aircraft missile, so he nodded:

"I had a phone call with Song Gong just now, and I almost forgot about it, how is it?

"This ........." The secretary hesitated for a moment, then handed the information forward, and said noncommittally: "Mr. Lu, you better see it yourself!"

When Lu Jiadong heard this, he didn't care, and the direct result was that the information turned two pages, and his smiling face suddenly froze on his face, and then said with some annoyance:

"Why is it less than the success rate of the fourth layer? Why don't you ..........report such a big thing?" (To be continued.) )
