Chapter 20 Frequency Conversion

It's not that the stealth circuit board isn't used, it's just that it's not used on Boss Ye's spaceship.

When Boss Ye's spacecraft made the final preparations before the test flight, at a military airport far in the southeast, four J-1 planes were speeding up and taxiing on the runway, and after running less than 100 meters, they both took off and sprinted towards the sky; If that light movement were seen by the Sukhoi family, it would definitely fall off their glasses; Then he scolded angrily: Damn rabbit, I actually changed my plane, but it was even better than the original, you must know that your ultimate Su Sanwu can't reach this level of short take-off and landing!

"Dong Yu Dong Yu, this is the tower, and your task is to escort the two H-6 test planes flying west around Feibao Island; The test machine has arrived in the designated airspace and immediately went to the rendezvous. ”

The final order was not given until all four planes had lifted into the air. However, the long plane leading the team was not surprised, since the level of the Rabbit family's navy and air force has been greatly developed, and the air force has successfully circled the treasure island for the first time; The military found this tightrope cruising method very cool, so flying around the island became a normal task of the Southeast Air Force; If there is nothing to do, large and small military planes will fly around the bay of the treasure island. The pilots of the four Jian-11 fighters who served as escort missions this time are all veterans who have experience in circumnavigating the island.

At the same time as receiving the command from the tower, a coordinate was transmitted to the screen of J-11. At a glance, the long plane is not far away in the open sea.

"Dong Yu received it and immediately went to the designated airspace. Escort the test machine around the Treasure Island. ”

It was the first time to escort a plane that flew straight from Sanqin; After all, the distance is so far, although it is no problem for the sixth master to complete the maximum voyage of 9,000 kilometers, but flying from Xi'an, and then crossing the Miyako Strait, and circling Feiduwan is a big variable on the road; plus flying at sea, or in the open seas where eagle sauce is rampant; No one can guarantee that there will be no accidents.

Of course, the military order has been issued, and these things are not on the consideration of the fighter pilots, they just need to complete their mission!

After recovering the tower, the four Warhawks thrust and headed towards the target area, looking at the speed far beyond the design, it was definitely a facelifted model with an anti-gravity circuit board.

Ten minutes later, the four planes arrived in the airspace of the Finger Earth.

The KLJ-A radar turned on the tracking + search mode, and scanned every suspicious target in the airspace with full power, but unfortunately nothing was found in a circle.

"Tower, we have reached the target area, and the radar has not detected friendly forces. Friendly forces didn't arrive on time! Repeated, friendly forces did not arrive on time. ”

The long plane can only think so, because with the size of the sixth master and the design of not stealth, not to mention the latest active phased array radar equipped by J-11, it is an old-fashioned Doppler radar, which can be easily observed and captured thousands of miles away. Therefore, if the radar can't find it, it can only be that the sixth master is late.

As soon as the debriefing was finished, a communication came in.

"Comrade, don't talk nonsense; Our bomber pilots have always arrived at the exact location on time and to destroy the target accurately; There was never a saying of being late! Look up, we have been waiting for you for a long time. ”

When the pilots of the four Jianyi heard this, they all raised their heads and searched the blue sky with their eyes. If you want to talk about the pilot's eyesight, that's pretty good; Soon, the crowd noticed two yellow dots on the top of their heads, different from sky blue; The visual distance does not exceed five kilometers.

"Impossible!" The long plane shouted in surprise: "Call the tower, the aircraft radar is malfunctioning!" You can't find the sixth master five kilometers away! Repeated, radar failure. ”

As soon as the tower heard that there was a malfunction, it immediately became nervous, and if the radar could not work normally, then the Jianyi would be blind when he ran to the open sea, let alone dealing with the enemy, and self-protection would be a problem. You can't let a sick plane keep working. The pilot immediately asked according to the emergency plan: "Dong Yu Dong Yu, this is the tower, can the fault be eliminated." ”

As soon as he finished speaking, the three wingmen also reported that the radar was not working properly, but one fighter said:

"The radar didn't find the sixth master! But the closest to us was a passenger plane 70 kilometers away, and the radar could identify that it was a Boeing 3! ”

When the long plane looked at the radar signal, it was really that in the distance that the radar could detect, there were at least seven or eight aircraft signal feedback, which was dozens of kilometers near and hundreds of kilometers away; But I just didn't look at the sixth master who was close at hand.

The pilot of the long plane immediately thought of a possibility, gasped, and reported:

"Tower, the radar is faultless, but the sixth master can't be found! Repeated, no fault with the radar. ”

The crew of the sixth master, who monitored the dialogue between the fighter plane and the tower through wireless signals, couldn't help but laugh after hearing the report of the long plane. The newly installed stealth equipment was not used to deal with the enemy, so he brushed his own people first.

The captain of the No. 1 crew leading the team held the intercom and said: "Please note that our plane will open the data link and turn on the friend or foe identifier. After cutting off the call, he said to the newly added electronic operator: "Turn off the stealth device's countermeasure to the L-band; Otherwise, our comrades-in-arms will think that their radar is broken. ”

After the data was shared on the fighters, two large radar reflections appeared on all four radars.

The pilot of J-11 breathed a sigh of relief, Nima, this is the radar reflection section that a normal sixth master should have!

After confirming the enemy and us, the four Jianyi began to escort the two six masters.

The six-plane formation soon left the inland sea and flew towards the Miyako Strait.

"These two bombards must have changed their magic." A wingman pilot said: "The flight speed just now is about to break the sound barrier, and I estimate that if it were not for the limitation of structural strength, this cargo would have to fly at supersonic speed." ”

The long plane looked sideways at the sixth master who was surrounded by four Jianyi one by one, and said: "You can get the cruising speed of Mach three by one of the Jianyi you fly, what is wrong with the high subsonic flight of the sixth master?" ”

The second wingman interjected: "In my opinion, the biggest change of this sixth master is probably not in speed, after all, its design structure is not suitable for supersonic flight; Its biggest improvement is still in the bomb load, if I'm not mistaken, there are twelve long swords hanging under the wings of these two six masters. ”

"I'll take a look!" The third wingman pilot, who had not spoken much, pulled the control stick, and J-1 rolled under the belly of the sixth master and flew upside down.

"One pair, three pairs, six pairs. It's true, it's not that the sixth master can only hold six long swords, today these two are amazing, and they have been doubled directly. ”

At this moment, the long plane spoke: "Don't be weird, we are about to cross the Miyako Strait, and the footbasin chicken that flies with us is coming!" ”..

And on the Yellow Shell Bomb Six, the electronic operator shouted: "Band radar wave detected!" ”

The band is commonly used by the early warning radar of Eagle Sauce, which is the radar of Eagle Sauce searching for targets.

The captain didn't look back and ordered: "Group A stealth circuit jumps to the band!" ”

The electronic operator replied: "Group A stealth circuit has been automatically jumped!" ”

The stealth circuit worked, and the two H-6s disappeared from the radar of the Eagle Sauce family.

Before it was over, the electronics operator shouted again: "The S-band and the band appear at the same time." It is the radar of the footbasin home! ”

The captain turned around this time and said, "Group B circuit and group circuit counter. ”

After the order was given, he was praying to Ma Enlesmao in his heart that several sets of stealth circuits would not interfere with each other. Although no problems were found during the ground test, it was only a ground simulation after all; This is the first time that this kind of test has been put into practice.

Fortunately, the pioneers of the column are powerful, and the radar waves of the S-band and the band are regarded as nothing, and they directly penetrate the past.

It's just that although Bang Liu has made himself invisible, J Yiyi is as bright as a star on the footbasin and the radar of the Eagle Sauce family. All of a sudden, the air base of the footbasin chicken was alarmed; The senior officials of the air base who were on leave were pulled by the alarm bell to the control tower. While cursing the hateful rabbit viciously, they gathered the news and closely followed the dynamics of the rabbit group.

"Radar confirmed, four Sukhoi fighters."

"The satellite is adjusting its orbit and there is no image support for the time being."

"The Allied Eagle Sauce has taken off the -3 aircraft to go to detect, and the commander of the Eagle Sauce Air Force garrison has asked our fighters to take off and approach for reconnaissance."

Fortunately, it's not the first time that the rabbit has flown around, and everyone is used to flying a few times a month; The work was carried out in an orderly manner, and when the information from all parties was gathered, the air command ordered the corresponding four F-2s to take off and accompany them.

The 3, which had already risen into the air, was hanging far behind the J-11, after all, it was just an electronic warfare aircraft, and in the face of the four J-11 armed to the teeth, the -3 of the Eagle Sauce family dared to hang far away, and had no courage to run in front of the J-11 to show off his might.

Inside the plane, Jerry, who was in charge of the radar data, suddenly frowned and said, "Hey, Tom, the data is a little wrong!" ”

Tom, the team leader, was busy with his own business, and when he heard this, he turned his head and said, "Jerry, what have you discovered?" ”

Jerry pointed to his monitor and said, "According to the data provided by the weather satellite, there should be a large cloud layer in this area now, and there will be rain in the next 2 hours." But now our weather radar shows a huge gap here. The original cumulonimbus clouds seem to have disappeared. ”

"Hmm," Tom thought for a moment, "could it be that the rain has already started to fall, and the cloud has fallen?" ”

"Impossible! With the pressure and the intensity of the warm front in these places, the rain will fall to the coast of the mainland, and it is impossible for it to disappear while still in the sea. "Jerry is still quite confident in his profession.

Tom said again: "The clouds won't disappear, but there are no clouds on the radar, could it be that they were eaten by the red rabbit?" Comang, Jerry, please find the reason for the radar, it could be a radar failure, or a data error! Why don't you look at it in a different band? ”

Again, Jerry nodded, looked at his screen again, his fingers crackling on the fixed keyboard.

On the H-6 plane, the electronic operator immediately reacted: "The detection band detection wave is being converted, and the group stealth circuit starts the automatic tracking conversion." ”

After receiving the frequency change, the signal receiver immediately feeds back to the data processing system, and after processing and calculation, the corresponding voltage and current of the stealth circuit board are obtained; Then the parameters are handed over to the controller of the stealth circuit, and within a few milliseconds of the frequency change of the detection wave, the stealth circuit changes the stealth frequency synchronously.

And so.

"It's been changed several frequency bands, and that shit cloud hasn't been detected, Tom, it looks like our radar is really broken!"
