Chapter 159： Advantages of Phased Array Radar

Facing the Soviet plane that fired missiles at them, the Tomcat fleet did not return. Just kidding, the other side has one plane and four of their own, can they still be frightened by the other side?

If you turn your head and run like this, it will simply embarrass the entire Fifth Carrier Air Wing! Don't be stationed on the aircraft carrier in the future, just stay in the rear as a reserve wing!

The lead plane's radar quickly locked on to the other side, and then, the flames flickered under the wing, and two Phoenix missiles flew out. ???One?Fiction?????????

Two salvos, aiming at one target!

The opponent actually fired four missiles! Want to attack four of your own fighters at the same time? ridiculous! Even the technology of the United States has only carried out the operation of attacking six targets at the same time in the experiment, and the results obtained are very ideal, but unfortunately it is only ideal!

In actual combat, there will be no enemy aircraft as targets, do not change any heading, waiting for the Phoenix missile to shoot down, if the cruise missile is similar!

Now, after the opponent fired the missile, the Tomcat fighter formation also began to maneuver. Except for the leader who had to aim the nose at the opponent to conduct mid-range guidance for the Phoenix missile, and could not move, the rest of the fighters began to maneuver. dodge.

A Tomcat fighter climbed high and rushed to an altitude of 20,000 meters, one to the left, the other to the right, looking at the opponent's backward radar, how to continue to lock itself!

The radar antenna needs to be aimed at the target before it can be locked. Just now, the four fighter planes were in the same direction, and it is possible to be locked by the other party at the same time. Now, as they spread out, the other party must make a choice, which direction the radar antenna will move. ! You can only stare in one direction, and you have to miss the target in the other three directions!

Unfortunately, they still miscalculated, because they did not expect that the radar of the other party was not an upside-down lid at all, nor a flat slot like theirs, but a phased array radar that changed the beam by a phase shifter!

The 3ooo ferrite phase shifters of the sBe-16 phased array antenna radar start to change the direction of the beam quickly. The beam radiated by the entire antenna is divided into four directions, and continues to track the target just locked and the opponent's maneuver. In front of the radar of sBe-16, it is the performance of the clown!

After the R-33 missile is fired, plus the degree of the carrier, it is as high as Mach 5, and it is in flight. With the effect of air resistance, the speed is constantly decreasing. When it reaches the target, the speed has been reduced to Mach 3. Even so, it takes less than 100 seconds to fly the distance of 90 kilometers!

The Tomcat is changing its orientation, but it cannot escape the search range of the MiG-31 radar!

Scan plus or minus 7o degrees vertically, plus or minus 6o degrees horizontally, a target inside a broad cone. Can't escape the hunting of MiG 31!

After the missile was fired, the MiG-31 turned off the afterburner, which increased the range of airspace scanned by the radar.

"Thirty seconds, ready to switch to the final semi-active guidance." Fedotov in the rear cabin said as he flipped the switch.

Although a powerful phased array radar is used, the electronic system of the MiG-31 is still quite complicated. Guiding the R-33 missile requires manual intervention in the whole process to improve the attack efficiency.

The guidance of the R-33 missile is divided into three parts, when it just flew out. It is controlled by the program, and then uses the radio command to correct the trajectory, and then uses the radar echo received by the target for tracking after approaching the target.

Semi-active radar guidance means that the missile only receives the radar beam. Do not shoot, rely on the carrier to illuminate the target, just like using a flashlight in the dark night, and then walking along the flashlight.

"Ten seconds countdown." Fedotov counted down: "Nine, eight..."

R-33 missiles, scattered in the air. Fly towards the four targets, and the one aiming at the leader of the other side is the first missile fired!

When being targeted by a missile and maintaining the same flight attitude as a target drone, when conducting medium-range guidance for one's own missile, it is the time to test a pilot's endurance most.

At this time, the pilot of the lead plane, Major Hustrang, felt that the sweat on his forehead was about to come out.

"Already switched to active guidance!" shouted the radar operator in the rear cabin.

The Phoenix missile is the first type of active radar-guided missile in the US arsenal. When it is 20 kilometers away from the target, the active seeker is turned on. At this time, the carrier can retreat!

"Okay!" Major Seustrang pushed the nose and began to dive down.

The electronic technology of the Soviets was backward, and the radar lacked effective ground scanning capability. Therefore, Sustron chose to dive down to avoid it. Moreover, the other three planes flew upwards and left and right respectively. As long as he went down, both Being able to get rid of the opponent's missiles can also give other wingmen more opportunities to get rid of the missiles.

Unfortunately, he was still wrong.

The 3ooo phase shifters of the phased array radar must have strong data computing capabilities. The processing capability of the MiG-31 radar is also higher than that of any previous fighter radar, and the ability to filter ground clutter has also been obtained. strengthen.

Moreover, the dive degree of the Tomcat fighter is not comparable to the flying R-33 missile.

"Boom!" Just after the R-33 missile continued to fly for ten seconds, it was already close to a distance of 20 meters from the Tomcat fighter. At this distance, the proximity fuze of the R-33 missile ignited 47 kilograms The ********, the flying broken rod warhead, brought countless fragments to the death of the Tomcat fighter.

"The target has disappeared." The radar operator said while focusing on the three missiles in other areas. At the same time, there were more than 700 phase shifters available to spread the beam and provide a certain airspace scanning performance.

"Two phoenixes are flying towards us, a distance of fifteen kilometers! It is expected to arrive in fifteen seconds!" Fedotov looked at the extra light spots on the radar screen and shouted.

Phased array radar is not omnipotent To guide four missiles at the same time, it is necessary to disperse the radar beam in four directions, and it will lack the ability to observe other airspaces. Therefore, this MiG-31 There were no two missiles from the other side.

But now, the vacated phase shifter uses the radar beam to scan the sky, and suddenly there is an abnormality. The other party is not only evading, but also shooting missiles to attack itself!

"Continue to guide." Andre shouted loudly towards the back.

Fifteen seconds is enough time!

The second missile, five seconds later, hit the second target aircraft.

"The third missile is malfunctioning! Prepare to guide the fourth." Fedotov shouted loudly. The missile was flying well, and suddenly fell when it was still two kilometers away from the target.

At this moment, he felt a dizziness in front of him, and his body turned upward at a large angle. Under the action of the anti-G suit, the blood in Fedotov's body was constantly flowing back, and he felt the large overload maneuver of the fighter. Andre in the cabin has already started to operate the fighter to maneuver to avoid the two incoming missiles. (To be continued.)
