Chapter 2358

As night fell, the sea waves were gently rolling and beating the hull, just like a lullaby.

It is an instinct formed by human evolution in hundreds of thousands of years, but now, it is still brightly lit on warship 167.

Above the hangar at the tail, there is a rack like antenna. The antenna is rotating, radiating countless electromagnetic waves into the air, watching the surrounding situation with vigilance.

Although the performance of phased array radar is advanced, it can not be turned on all the time. It is used for early warning most of the time.

Now, the formation of warships has retreated. Their escorts, scientific research ships and captured frigates, sailed near Yongxia reef. Before more ships pick up, the task of the formation is very heavy. They have to monitor the sky overhead and protect their own safety.

"Everyone cheer up. Our early warning plane has landed. There will be a gap of one and a half hours. During this time, we must be vigilant." Wei Jian shouted loudly.

Only one early warning aircraft can not provide all-weather early warning capability. It is best to use four early warning aircraft, but our Yongxia reef base can not deploy so many early warning aircraft temporarily. Therefore, there must be some empty window in the middle. If the other party wants to launch a sneak attack, this empty window should be the easiest to be used.

"Found a target, radiating electromagnetic waves!"

"Switch to passive mode!"

The people under their command are quite skilled in controlling the electronic system on the warship. The radar actively transmits signals and then receives signals. However, when necessary, it can also be turned into passive. If the target is radiating strong electromagnetic waves, passive reception may be easier.

Moreover, if it is received passively, the detection distance will be further. Take the E2 eagle eye for example. Active radar scanning is 300 or 400 kilometers, but the passive detection device on the aircraft can detect 700 kilometers away.

"At a distance of 450 kilometers, such a strong radiation source should be an early warning aircraft, and the target is near the coastline of monkey country." the radar officer quickly judged.

Monkey country, where did the early warning aircraft come from? It must have been sent out by Xiong people! Since the early warning planes of Xiong Guoren have been pulled out, what does that mean? Xiong Guoren is helping!

Damn bear! Two faced guy.

"Inform the base immediately that the next attack of the monkey may come, and there may be the help of Xiong Guoren!"

The monitoring distance of Xiong's early warning aircraft is also limited. The other party is far away, which is afraid of being detected by its own radar. At the same time, although the other party's radar can't scan the fighters in its own sky, it should be able to monitor that its own early warning aircraft has returned, so the opposite party should go out!

"The warship's phased array radar is activated to activate our ship to air missiles and be ready to intercept!" Captain Wei ordered one by one. At the same time, when the news reached Yongxia reef base, Chen Rui, who had been waiting for a long time, immediately got excited, took his helmet and rushed out.

"I'll go up and have a look," Chen Rui shouted.

The deployment of fighters must be planned well. It is not cost-effective to take off in large numbers too early. It will consume valuable fuel. If you wait until your fleet takes off, you don't find anything. As a result, when you land, the other party will launch an attack, and it will be too late for your side to send out again.

In the current situation, Chen Rui's observation alone is the best. The people below are waiting at any time.

At this time, the early warning aircraft is also refueling, routine maintenance and preparing to start again. Chen Rui goes up first and takes up the gap period is enough.

The black J-11B fighter entered the dark night sky. Chen Rui suddenly found that his fighter was more suitable as a special night fighter. At night, if he didn't turn on the radar, the other party couldn't even see his own in the airspace a few kilometers near him.

Of course, unless he doesn't turn on the radar, now, after taking off, Chen Rui can't wait to turn on the radar, scan it in the direction of the coastline of monkey country, and then say: "the ghost reports that no fighters flying at ultra-low altitude have been found for the time being."

Pulse Doppler mode, sea search. In this case, the radar of the base can also detect targets flying from high altitude. If the other party comes, it is definitely ultra-low altitude. Chen Rui comes up now as an early warning aircraft.

In fact, the male cat fighter in those years was absolutely competent as an early warning aircraft with a search distance of up to 300 kilometers. The radar on the nose of the current J-11B naturally also has this ability. Moreover, due to the development of electronic technology, it is more efficient to scan the targets in front.

"The other party's early warning aircraft is moving in our direction." the report came again from warship 167.

If you want to command a battle, the other party's airspace is still too far away, and the airspace covered by the airborne radar of the early warning aircraft is also limited. Although it is often hundreds of kilometers in theory, in fact, there are too many targets lost at a long distance.

The other party is moving, which means that the other party must be commanding the aircraft fleet and gathering towards his own side!

"The ghost continues to approach each other," Chen Rui shouted.

Unless the other side's aircraft are stealth aircraft, it is certainly impossible. As long as they are not stealth aircraft, ultra-low altitude aircraft, they also have the ability to find it!

Chen Rui pushed the joystick and the fighter continued to fly in the opposite direction. Sure enough, after another 50 kilometers, some snowflakes appeared on his radar screen.

"The ghost reported that the other party's aircraft group carried electronic jamming equipment, and my airborne radar was jammed. Now, the radar has changed mode."

The snowflakes on the radar screen are caused by electronic interference, which makes Chen Rui look forward to, indicating that the target is ahead!

Generally speaking, the electronic technology in the western world is more developed. Therefore, electronic countermeasures are all advocated by the West. It would be a big mistake to think that Xiong Guo has no electronic countermeasures. Xiong people prefer to use violence. If the electronic tube interferes with the pod, the power is super large.

However, it's just high power. If you want your radar to enhance its anti-jamming ability, you definitely don't use any power means, but use fine electronic technology. Specifically, it is to enhance the main lobe energy of radar radiated electromagnetic wave and reduce the side lobe, because it is carried out on the side lobe during jamming.

Now, after switching the mode, the interference is reduced.

Many bright spots appeared on Chen Rui's screen. He glanced briefly and reported: "find the target, the number is about 30, the distance is 150, repeat, find the target!"
