If you take it apart, you will have an orange and yellow tablet inside, which seems to be more high-end, but now it can only be displayed to this extent.

If you dismantle the fiery red reflective antenna outside, you will have to use a crane, this thing is not light, and there is a frame inside.

If you wait until later, after the introduction of the Su-27, and disassemble the nose of the Su-27, you can see that the appearance of this radar is almost the same, but the paint is different.

Of course, for the country, this radar is absolutely advanced, after all, the caliber of this radar is still good, compared to the small radar rangefinder in the air intake cone of the MiG-21, this thing is very strong.

Everyone is looking at it with happy eyes, especially Mr. Gu, if this radar is installed on the latest J-8 fighter with air intake on both sides, it will definitely have a radical change immediately.

"There are several modes of this radar, and for today's test flights, we need to have target aircraft. In this way, the performance of this radar can be effectively detected. Colonel Mido stood aside, looking at the appearance of everyone, and began to introduce, he pointed to another fighter plane on the side: "In a while, the Mirage F1C fighter next to us will act as a target aircraft." ”

Qin Feng looked over, the Phantom F1 fighter belongs to Dassault's special case, Dassault's favorite thing is the layout of the tailless delta wing, and this Phantom F1 fighter is a normal aerodynamic layout, and now, the wing of this fighter is also mounted with two large auxiliary fuel tanks.

This is, of course, to have a larger radar reflection area.

When talking about the specific data of the radar, it is necessary to indicate what the target is, so that it is effective, for example, the most perverted in this era is the Tomcat fighter, which has a terrible maximum search range of 315 kilometers when using the powerful AWG-9 radar.

However, this refers to the target of a large bomber like the Tu-95, and if it is a light small aircraft like the MiG-21, the distance is reduced by at least a third.

At the same time, how far it can be found is also related to the pattern of the radar.

At present, there are still very few radar models, and it is not until the development of pulse Doppler radar equipped with flat slot radar antennas that a variety of multi-mode detection methods will be available with the advancement of data processing technology.

Everyone gathered around the radar in the nose of the plane and studied it for more than 20 minutes.

Why did the West quickly abandon the layout of the nose air intake? It is to free up the nose of the aircraft and place a large-caliber radar, the antenna of this airborne radar is almost close to the diameter of the nose of the carrier aircraft, so as to maximize the effect.

After the visit, Qin Feng and Colonel Mido walked into the cabin, it was still Colonel Mido who sat in the rear cabin, Qin Feng was in the front cabin, and when he sat down, a kind of excitement emerged in Qin Feng's heart.

If you want to fly an airplane when you see it, it's a good plane!

Compared with domestic fighters, this aircraft is definitely something to look forward to.

At this time, the radome in the nose had already been closed by the ground crew, and in the eyes of everyone, Qin Feng operated the fighter, slid onto the runway, and began this test.

Before they took off, the Mirage F1 fighter had already slid onto the runway, and looking at the flames spewing out of its tail, Qin Feng also released his brakes and slid towards the runway.

Soon, the Mirage 2000 fighter took off into the air, and Qin Feng's hand flicked the switch to warm up the radar.

Some military magazines say that Soviet radars have always used electron tubes as the main element, and at the same time, Western radars have begun to develop towards microelectronic technology.

Radar antenna is to radiate electromagnetic waves, no matter what kind of antenna is used, even if it is the most advanced flat slot radar antenna, behind it, there is still a source of electromagnetic radiation, which is the magnetron.

The magnetron is an extremely special electron tube, in which the direction of electron motion, the radial direct current electric field and the axial constant magnetic field are perpendicular to each other and are used to radiate electromagnetic waves.

Early magnetrons were extremely inefficient and had no practical significance. Until the advent of multi-cavity magnetrons, and in time for World War II, multi-cavity magnetrons were widely used in military radar transmitters and played a great role.

Until now, it is still this way, there is no essential breakthrough, and it is not until the later stage, after the use of active phased array radar, that there is a new principle.

So, as long as it's a tube, it needs to be warmed up.

In fact, this is nothing, the shooting sight of the cannon aiming that is still widely used in China also needs to be warmed up, for the pilot, if he encounters a combat mission, then he must turn on the switch and warm up first, which is already a Xiguan.

"First test project." Colonel Midow in the rear cabin said: "The altitude is 9,000 meters, and the attack maneuver is carried out in the upward view tail chase mode. ”

The target machine is higher than yourself, you need to look up, this is the upward view, the target machine is lower than yourself, that is, the downward view, the upper view is based on the blue sky as the background, quite relaxed, at this time, it is the easiest way to attack.

The early bombers all pursued high-altitude and high-speed penetration, which was the easiest time to be intercepted.

"Understood, the height is nine thousand, the upward view is tail-chasing, and the scanning mode is scanned."

The so-called tail chase, that is, flying in the same direction, your own side chasing from behind.

In the previous mode of warfare, it was mainly guided by the ground, so that its own interceptor aircraft could easily cut into the rear hemisphere of the opponent to attack, which was also the Soviet Union's combat mode, interception under ground guidance, and for the West, the pilot's initiative was more encouraged, so the detection ability of the pilot's own airborne radar equipment was more important.

Qin Feng adjusted the radar mode to this attack mode, at this time, the downward-looking display on the dashboard became the radar display, and when he turned on the radar, a bright line swept across the screen, and soon, a point of light appeared.

"Intercept the target, eighty miles away." Qin Feng shouted.

The target 80 kilometers away is not visible to the naked eye, and this is also the first time that the Chinese Air Force has operated a fighter plane and intercepted the target at a distance of 80 kilometers!

After discovering that it was intercepted, the target's Mirage F1 fighter turned on the afterburner and accelerated in the sky, the distance between the two sides became larger and larger, and the bright spots on the radar screen, the numbers next to them were also increasing.

When the number increases to one hundred and two, the highlight of the goal disappears.

This means that for a target like the Mirage F1, the maximum search distance is about 100 kilometers, of course, in this mode, and the distance will be very different in different modes.
