The staff of the test flight institute behind Shen Yan did not add fuel to the fire, but just buried their heads in recording all the data and the situation just now.

Of course, the act itself has caused a lot of damage to the former's heart.

But the testing process is not over yet, so no matter how uncomfortable Shen Yan feels in his heart, he still has to command the troops to complete the next tasks according to the plan.

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

Moreover, judging from the skillful performance of the commanders and fighters of the battalion under his command, the next few tests may not have a chance to turn the tables.

There must be a limit to the radar's capabilities, but whether the test is successful or not is originally a matter for the aviation industry, and he, Shen Yan, as the commander of an antiaircraft artillery regiment, is now only thinking about how to shoot down the simulated "enemy plane".

Taking advantage of the time when the plane circled, he lowered his head and pondered for a while, then picked up the walkie-talkie again and connected to the battalion commander who was sweating on the position:

"Inform me, let the gunner stay in the battle position the whole time this time, if there are still 6 false targets in the first round, then don't fire, wait until the real targets appear later!"

The battalion commander, who was already a little panicked, heard the calm voice of the regiment commander coming from the walkie-talkie, and his mentality instantly calmed down a lot, and he began to redirect the troops to reload and reset the artillery, waiting for the next round of tests to begin.

On the one hand, he had already experienced an electromagnetic interference and knew what the situation was about to face, and on the other hand, in order to ensure safety, the Y-7 aircraft could not simulate the low-altitude and high-speed penetration of a real attack aircraft, so it could only fly slowly and leisurely in the middle of the air, which also gave Zhu Yuan and enough time for manual manipulation.

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

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

After all, they are not really the Blues to engage in confrontation, they only need to be responsible for recording the situation of the radar in the face of interference, and whether the latter plays these tricks are successful or not, in fact, will not affect the test results.

About ten minutes later, the transport plane, which looked a little clumsy because of the two pods, returned to its "attack course".

Everything seems to be a repeat of the last time, only this time there are many more fighters operating anti-aircraft guns on the position.

"Report, radar found target!"

The radar operator again reported loudly.

A smile finally appeared on Shen Yan's face.

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

However, two seconds passed, and he still did not hear the specific information about the target.

"What's going on?"

Shen Yan, who was sinking in his heart, turned his head and strode behind the radar operator, looking at the circular screen in front of him

"How?"

Instead of a number of false targets in front of him as neatly as last time, there were anomalous signals scattered throughout an entire strip of area!

"Try it, can you lock it?"

Shen Yan, who was relatively confident just now, was completely bottomless this time.

Although he didn't use all the ammunition at the fake target as he did the first time, the direction of the entire position was now chaotic on the radar screen, and he couldn't even determine the specific location of the target.

Even in the air defense operations of World War II, it was necessary to give early warning of the approximate direction, altitude and time of the attack of enemy aircraft.

Countries with good conditions use radars, and those who do not have such conditions also have full-time air defense lookouts to conduct reconnaissance several kilometers away from their positions and even in the middle of enemy planes' routes, in order to give the air defense units sufficient time to react.

If the anti-aircraft artillery observers had waited until the target was visible to the naked eye before reacting, it would have been too late.

Like now.

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

And the height is a little lower than last time.

So much so that the rangefinder who was staring in one direction didn't even spot it in the first place.

By the time 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 sides.

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

You must know that the divisional antiaircraft artillery regiment is responsible for the air defense task of an entire division-level position, and only one battalion can be deployed in each direction.

“TMD！”

Shen Yan slammed his fist on the table beside him.

At the same time, Chang Haonan, who was in Yanliang, was also following up to understand the movements of the test site.

Although the specific data needs to wait until the test is fully completed before it can be analyzed, the basic situation can still be obtained in real time by phone.

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

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

But in terms of effect, there is no need to repeat it.

The range of the Y-7 is not outstanding, not to mention that it also carries two pods, one large and one small.

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

At the very least, this proves that it is possible to replace a high-performance component that is temporarily unavailable with multiple components with slightly inferior performance in the case of architectural leadership.

The train of thought is no problem.

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

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

Pod 2 is the redesigned pod that is more compact, and 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, on the position of Hongnong's anti-aircraft artillery regiment, everyone, including the regiment commander Shen Yan, became depressed.

Despite knowing that there were still two sets of tests to complete, the previous fighting spirit inevitably began to dissipate after trying all means to catch the target.

Later, it is just a step-by-step cooperation with the test flight institute to complete the test task.

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

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

"Commander, the interference has suddenly weakened!"

"What's going on?"

Shen Yan instantly lifted his spirits.

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

The operator replied as he quickly adjusted the equipment.

"Quick, all attention, auto-fire mode, ready!"

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

"The target is in range!"

"Fire!"

The two rounds of simulated shooting were completed quickly, and according to the normal drill setting, this was considered a complete shootout.

The fourth round of testing that followed, and the situation was almost identical.

Despite the fact that the multi-coverage interference initially succeeded in obscuring the position of the carrier aircraft, it was locked at a distance of about 6 km.

Although this distance seems to be very close, it is important to know that the Sight 10 is not a very good radar, and it can be caught by it at a distance of 5-6 km, then the situation is obviously not optimistic when facing more advanced and powerful models.

Now, the atmosphere on both sides has been reversed.

"Captain, we're half the winner?"

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

The latter turned back:

"Count, count, they all say that we are air defense and air defense, and now we have only been empty twice in four defenses, counted!"

"Ahem...... Then tomorrow ......"

"Inform the cooking squad of each company that they are going to kill the pigs tomorrow, and the whole group will have a meal!"

"Huh?"

The face of the secretary of the canteen of the regiment organ, which was still jubilant just now, froze instantly, and immediately showed a painful expression......

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

The first pod tested earlier was the same large pod that was a 1:1 replica of the seized model, and everything was fine.

Pod 2 is identical from an equipment point of view, but its performance is a cut short.

The 713 is specially strengthened for the purpose of testing electronic equipment, and it is certainly not caused by insufficient energy......

"Shhh...... Is it really necessary to be cautious about modifying the original design? ”
