The two pod prototypes were built several days earlier than previously expected.

This is not unexpected, after all, everyone who has been Party B knows that when writing the deadline, it must be on the basis of the normal schedule and a period of grace just in case.

Chang Haonan and Xu Yang came to the production workshop from the dormitory area as soon as they got the news.

Two pods, one large and one small, were lying quietly on the specially designed brackets for them.

Although the engineering prototypes are still in very rough condition, it is still possible to get a glimpse of what they will look like in the future when they are actually finalized.

There is nothing to say about the large pod, it is just an equal scale copy of the seizure, but the components and part of the program code are replaced according to Chang Haonan's design.

The synthetic aperture radar that originally occupied the middle of the pod had been handed over to another group, and the test did not involve radar reconnaissance, so it was replaced with an equal-weight and equal-large counterweight to prevent the pod from being too heavy at both ends and too light in the middle, and there were structural problems in the air.

The small pod, on the other hand, is much better, as it is designed as a long strip with a curve around it, considering that it will be carried by a tactical aircraft under the wings.

And in order to ensure compactness, a shock generator of smaller volume and power was chosen, which was installed in the tail of the pod instead of the head through two air intakes, so as not to interfere with the transmitting antenna here.

The overall appearance is similar to that of the K/RKL800 large electronic jamming pod (export model KG800), which was commonly equipped with heavy fighters and bombers in previous generations.

The only price is that it can't be powered entirely by itself like that large pod, and it needs to be partially supplemented by the carrier aircraft.

However, it is not a problem for the J-8C with a power generation of 18kw*2 and the J-7 with a power of 15kw*2.

Not to mention the domestic flanker family with a power generation of up to 30kw*2 or even higher in the future.

"Good stuff, good stuff."

Chang Haonan patted the pod shell in front of him, which looked a little like a half-finished pod, and was quite satisfied.

In the previous life, the Chinese Navy and Air Force suffered enough losses from the Americans' electronic warfare equipment in the naval and air confrontations for quite a long time.

And now although they have an additional interference pod, everything is difficult at the beginning, with a breakthrough from 0 to 1, and it will be logical to go from 1 to 10 and even to 100 later.

"By the way, what about Guo Gong?"

Chang Haonan was just about to call for people to conduct a ground power-on and signal input and output test, but after looking around, he found that there was no Guo Lin.

In fact, everyone rushed over temporarily after receiving the news, and many people haven't had time to get in place, but Guo Lin usually eats and lives in the office, so he is often the first to arrive when there is anything, and it is a bit strange that he didn't see others for such a big thing as the pod going offline today.

Guo Gong...... I don't seem to have seen Guo Gong today? ”

Someone thought for a moment and then said.

"I remember that Guo Gong seemed to say that his younger brother came to Jinling to join him two days ago, maybe he was arranging for his family, right?"

“……”

Just when everyone was saying a word, the panting Guo Lin finally appeared at the door of the workshop.

"It's all there?"

Guo Lin took a look and found that he was the latest among the basically more important people, so he couldn't help but explain:

"There is a relative at home, who took half a day off today and just came back from outside."

For this kind of thing, Chang Haonan didn't have too many thoughts to gossip, and after Guo Lin calmed his breath, he announced the start of the test.

"Preparing for the first round of testing, ladder wave frequency shift, jammer starting modulation frequency 1MHz, interval 0.4MHz, dry signal ratio 8dB, 10 segments of pulse ......"

Considering the resolution of the detection equipment, in order to facilitate observation, it will not really use the frequency of 10Ghz, which is actually equivalent to a basic program debug process, mainly to detect the basic logic and algorithm functions of software and hardware.

The process is not complicated, but it is time-consuming.

According to the pre-assigned tasks, several crews quickly began to adjust the settings of the jammer and signal generator.

Chang Haonan also stepped aside, ready to look at the waveform displayed on the oscilloscope screen.

At this time, I happened to hear the conversation between another engineer next to him and Guo Lin.

"How are you going to arrange Xiao Yu?"

Listening to this tone, the two should be more familiar, combined with the fact that Guo Lin has a younger brother who came over to defect to him, so it is not difficult to guess the identity of this Xiao Yu.

"Let's find him a helper to do first, and then see if there can be a more suitable job."

Guo Lin replied with a soft sigh.

"Don't worry too much, your brother has that fitter's skills, is he still worried about not being able to eat on our side?"

Another relieved:

"When this time is busy, I will ask your sister-in-law to go to Nanqi to inquire, they said before that there is a shortage of work."

"It's not a question of whether you can eat or not."

Guo Lin, who heard his friend's comfort, said with a wry smile in his tone:

"He changed his age after graduating from junior high school at the age of 15, and took my father's class to work in our cable factory, if you really want to see the household registration, it is actually my brother, it has been fourteen or fifteen years, and he has never left the factory, and now he suddenly received a notice to be laid off, I am afraid that he will not be able to turn his mind......"

It is another story of helplessness under the tide of the times.

Chang Haonan suddenly remembered that during the winter vacation, his parents said that they would arrange a blind date for him.

Although he no longer has a clear impression of the name, the experience of dual-income families should generally be very similar.

In fact, even many single-worker families can't bear it, and in this year, relying on only one person's income will definitely not be able to support a large family.

At this time, with the sound of a drop, the test officially began.

Everyone turned their attention to the data and devices in front of them.

"Huh...... The quality of this fake target is very high. ”

Xu Yang stood behind Chang Haonan, looking at the signal waveform displayed on the oscilloscope, his tone was full of excitement.

"Yes, it's no wonder that the ground radar and the radar on our plane will be fooled......"

Chang Haonan nodded:

"7 false targets, 10 μs, 14 μs, 18 μs, 22 μs, 26 μs, 30 μs, 34 μs, and all the signal signatures are stronger than the real ones, except for the first one which is slightly weaker, I am a radar and I am confused."

Chang Haonan recorded all the data, and then quickly issued another order:

"Prepare the second stage, piecewise linear function frequency shift, start modulation frequency 1.5MHz, interval 0.4MHz, frequency modulation slope 20KHz/μs, dry signal ratio 8dB, 4-segment pulse ......"

A completely different signal appeared on the oscilloscope.

Unlike the large number of false targets just now, this time, the signal peak of the true target was overshadowed by a dense multi-segment coverage interference.

This is a mode that the original pod did not have, and it works well for some radars that are not absolutely powerful enough.

Xu Yang lightly waved his fist in the air - the idea of joining this mode was still proposed by her.

Copying is not to copy as it is, but to improve and develop on the basis of the prototype.

“……”

The ground testing process ended up lasting a full day.

The results were a great success at the predetermined test frequencies.

As for the more complex tests, since the 14 anechoic chambers are still under construction, they will only be seen in the sky.

"Lao Guo, get ready to fly Yan Liang!"

Chang Haonan recorded the last data on a piece of paper, raised his head and said to Guo Lin next to him.
