The military-industrial scientific research system of the academic master.

The few flight test institute staff behind Shen Yan didn't show any particular signs of exasperation. They just immersed themselves in recording all the data and situations just now.

Of course, this behavior itself caused considerable harm to the former's heart.

But the testing process is not over yet, so no matter how uncomfortable Shen Yan feels, he still has to command the troops to complete the next tasks as planned.

As for technical and tactical issues, we can only wait until the end of today.

Moreover, judging from the skilled performance of the battalion commanders and fighters under his command just now, there may not be any chance of a comeback in the next few tests.

There are definitely limits to the capabilities of the radar, but whether the test is successful or not is a matter for the aviation industry. As the commander of the anti-aircraft artillery regiment, Shen Yan is only thinking about how to put the simulated " "Enemy plane" was shot down.

While the plane was circling around, he lowered his head and pondered for a while, then picked up the walkie-talkie again and called the battalion commander who was sweating on the position:

"Notice, let the gunner stay in the fighting position the whole time this time. If there are still 6 false targets in the first round, then don't fire until the real targets appear later!"

The battalion commander, who was already a little panicked, heard the regimental commander's calm voice coming from the intercom, and his mentality instantly calmed down a lot. He began to re-direct the troops to reload and reset the artillery, waiting for the next round of testing to begin.

In fact, Shen Yan is suspected of taking advantage of a test loophole by doing this. On the one hand, he has already experienced electromagnetic interference and knows what kind of situation he is about to face. On the other hand, in order to ensure safety, the Y-7 aircraft cannot simulate the real situation. The attack aircraft's low-altitude and high-speed penetration could only fly over slowly at mid-altitude, which also gave Bisuan Zhuyuan and manual cannons enough time.

If the target is a Qiang-5 or JH-7, in fact, even with radar assistance, it is difficult for the muzzle to keep up with the approaching angular speed of the target by manpower alone.

Several engineers from the flight test institute saw all this, but did not interfere with Shen Yan's command.

After all, they are not really the Blue Army coming to engage in confrontation. They are only responsible for recording the radar's situation when it faces interference. Regardless of whether the latter's tricks are successful or not, they will not actually affect the test results.

About ten minutes later, the transport plane, which was a little clumsy because it had two pods attached, returned to its "attack route".

Everything seemed to be a repeat of the last time, except this time there were many more soldiers operating anti-aircraft artillery on the position.

"Report, radar found target!"

the radar operator shouted again.

A smile finally appeared on Shen Yan's face.

If the other party still uses his old tricks, he is sure to earn back his face this time.

However, two seconds passed, but he still did not hear the voice reporting the target's specific information.

"what happened?"

Shen Yan, whose heart sank, turned around, strode behind the radar operator, and looked at the circular screen in front of him.

"why is it like this?"

What appeared in front of him was not the same false targets as last time, but abnormal signals spread throughout the entire long strip area!

"Try it and see if it can be locked?"

Shen Yan, who was relatively confident just now, was completely at a loss this time.

Although he did not shoot out all the ammunition at the false target like the first time, the direction of the entire position was now in chaos on the radar screen, and he could not even determine the specific direction of the target's attack.

Even in air defense operations during World War II, advance warning of the approximate direction, altitude, and time of enemy aircraft's attack was needed.

Countries with good conditions use radar, but those without such conditions also have full-time air defense lookouts who conduct reconnaissance several kilometers away from the position, or even in the middle of the enemy aircraft route, in order to leave enough reaction time for the air defense forces.

If the anti-aircraft gun observer had to wait until the anti-aircraft gun observer could see the target with his own eyes before reacting, it would be too late.

Just like it is now.

As expected, the Yun-7 appeared in a different direction than last time.

And the height is even lower than last time.

So much so that a rangefinder looking in one direction wouldn't even be able to spot it in the first place.

When the 18 anti-aircraft guns adjusted their direction and aimed their muzzles at the target, the opponent had almost flown over the position.

Obviously, the best outcome is for both parties to die together.

But even if Shen Yan judged with the lowest standard in his heart, he couldn't tell himself that this was a successful defense.

You must know that the division-affiliated anti-aircraft artillery regiment is responsible for the air defense mission of an entire division-level position. Only one battalion can be deployed in each direction. If the opponent replaces one of his battalion-level positions with one aircraft, it means that the whole The division faced follow-up air attacks in this direction with its doors wide open.

"TMD!"

Shen Yan punched the table next to him.

At the same time, Chang Haonan, who was in Yanliang, was also following up on the developments at the test site.

Although specific data needs to be analyzed after all tests are completed, the basic situation can still be obtained in real time over the phone.

In fact, the two simulated attacks of aircraft No. 713 used two frequency-shift interference modes of the pod: advanced false target interference and multi-coverage interference.

Of course, the pod can also combine these two modes to generate false targets while shielding the real targets with coverage signals.

But from the perspective of the effect, there is no need to repeat it.

The range of the Yun-7 is not outstanding, not to mention it comes with two pods, one large and one small.

When the report of successful testing came out on the phone, the atmosphere in the entire conference room became heated.

This at least proves that with a leading architecture, it is possible to replace high-performance components that are temporarily unavailable with multiple components with lower performance.

There is no problem with the idea.

"The test of pod No. 1 will be here first, and the next round will start testing the effect of pod No. 2!"

Chang Haonan suppressed the same excitement and ordered to the phone.

The No. 2 pod is the redesigned, more compact pod that can be mounted by most tactical aircraft.

This is the product that Chang Haonan really has high hopes for.

……

Unlike the situation on Yan Liang's side, everyone on Hongnong's anti-aircraft artillery regiment position, including regiment leader Shen Yan, became depressed.

Even though he knew that there were still two sets of tests to be completed, after exhausting all methods and failing to catch the target, the previous fighting spirit inevitably began to dissipate.

From now on, it’s just about cooperating with the flight test institute to complete the test tasks step by step.

Even the radar operator's voice was much quieter when he reported the discovery of a false target again.

However, just when Shen Yan thought he was about to repeat the plot of the first test, the situation suddenly changed.

"Captain, the interference suddenly became weaker!"

"what happened?"

Shen Yan instantly became energetic.

"The echo intensity of the false target has become weaker, and I can distinguish the real target from it!"

The operator replied while adjusting the equipment quickly.

"Quick, everyone pay attention, automatic shooting mode, prepare!"

After all, the Y-7 is a target with a large radar reflection area and almost no maneuverability. Although the interference effect has not completely disappeared, the affected radar still completed the lock at a distance of about 5km.

"Target in range!"

"Fire!"

Two rounds of simulated shooting were completed quickly. According to the general exercise settings, this was considered a complete shootdown.

In the fourth round of testing that followed, the situation was almost exactly the same.

Although multi-coverage interference initially successfully obscured the aircraft's position, it was still locked at a distance of approximately 6 kilometers.

Although this distance seems very close, you must know that the Aim 10 is not a very good radar that can be caught at a distance of 5-6 kilometers. So when facing more advanced and more powerful models, The situation is obviously not optimistic.

This time, the atmosphere on both sides turned around.

"Captain, do we think we have won half the battle?"

The radar operator took off his earphones and looked at Shen Yan, who had just taken turns hugging the regiment command team.

The latter looked back:

"Okay, okay, they say we are anti-aircraft, anti-aircraft, and nine out of ten. Now we have defended four times and only missed twice, okay!"

"Ahem... then tomorrow..."

"Notify the cooking squads of each company to prepare to kill pigs tomorrow and provide extra meals for the whole group!"

"what?"

The face of the Secretary General of the Regiment Canteen, who had been beaming just now, froze for a moment, and then showed a pained expression...

On the other side, Chang Haonan, who had just learned that the interference effect of the No. 2 pod was not satisfactory, fell into deep thought.

The No. 1 pod tested before was the large pod that was copied 1: according to the captured model, and everything was normal.

Pod No. 2 is identical from an equipment point of view, but its performance is somewhat inferior.

Unit 713 has specially strengthened its power supply capability for electronic equipment testing. It is definitely not caused by insufficient energy...

"Hiss... Do we really have to be cautious when modifying the original design?"
