Chapter 237: Various Modes
At this time, a bright spot suddenly flashed on the screen, and Qin Feng knew that it was the other party who was turning.
When turning, the side of the fuselage will reflect more echoes, so that it is intercepted by itself again, of course, this is only short-lived.
The target has completed the turn and is in range of a head-on attack with allied allies.
"Head-on mode." Colonel Mido continued to shout. Just after the tail, now it is head-on, in different modes, although they are all using one of the most commonly used scanning methods, the radar also has different detection capabilities.
Because at this time, the reflection echo of the opposite fighter is different.
At this time, the RDM radar in front of the nose of the aircraft is constantly rotating, radiating electromagnetic waves into the surrounding airspace, because it is head-on, the relative speed of the two sides is very large, so soon a shadow appears on the radar screen.
"Seventy kilometers away, find the target."
"Move into tracking mode."
Scanning and tracking are different.
If scanning, the radar wave will continue to radiate to the surroundings and reflect back the bright spots, which means that there is a target, and if it is tracked, the radar will no longer scan the surrounding airspace, and all the electromagnetic waves will be irradiated to the target.
At this time, because the radar beams are all concentrated together, it is possible to obtain various data on the target, and only when the data is complete, can the missile attack be launched.
Qin Feng quickly changed the mode, there are two tracking modes, one is continuous tracking, in this case, it is only tracking, and the other is scanning while tracking, at this time, in addition to tracking, it is also scanning other airspace, so as not to have other enemy planes to sneak attack.
These modes, Qin Feng has long wanted to give them a try, in China, there is no such radar at all, the poor 204 radar, the search and interception distance is only 20 kilometers, and at this time it has long entered the scope of vision.
And now, at last, it is possible to try out the various modes of mainstream missile attacks in the West.
The Mirage F1 fighter flew overhead, and after the two sides flew past, they began to turn and test their performance in various conditions again.
In short, this radar as a whole still makes me feel satisfied, much better than the previous one.
"The last item, a head-on attack." Colonel Middo said.
All kinds of data have been measured, and now, there is only one last one left, the downward view attack!
"Understood, look down head-on." Qin Feng said, pushing the operating stick, and the fighter began to drop in altitude.
Among the various modes, Qin Feng actually values the downward view the most, because, according to his and General Lin's analysis yesterday, the downward viewing ability of this fighter should not be good.
In order to "denigrate" the Mirage 2000 and open the way for their F16, the radar of this fighter has been carefully analyzed.
The RDM radar, formerly known as Celaeno V, is just an improved version of the Celaeno IV, and it is still essentially a single-pulse rather than the Doppler radar as its name suggests.
Even if you don't use a flat slot radar antenna, it's not even a multi-pulse radar, it's just a single pulse, and this kind of radar can be said to be similar to the principle of your own 204 radar.
In this case, it may perform well at high altitudes, but low altitudes are definitely its weak point.
In modern warfare, ultra-low-altitude penetration has become a commonly used means, and if there is no downward vision ability, it cannot be regarded as a qualified radar system.
At this time, Colonel Mido was already calling the target aircraft on the radio, and the flight altitude of the target aircraft was one hundred and fifty meters!
In the naval battle that broke out not long ago, the Argentine Navy's super flag fighter flew at an altitude of only 10 meters, which is equivalent to flying close to the sea surface.
It can be said that the height of one hundred and fifty meters is not high, but Qin Feng is not qualified to ask people to continue to descend in height, and it will be dangerous to fly to 10 meters.
Maybe a wave hits up, or the plane suddenly loses control and falls directly.
Qin Feng looked at the meter in front of him, his height was three thousand, and the height of the target was one hundred and fifteen, which was definitely the category of looking down.
Now, see how this radar performs!
While flying forward, Qin Feng looked down at the monitor below, and at this time, he once again discovered the benefits of fly-by-wire control.
As long as the lever is not moved, the fighter will fly level.
In the previous fighters, as long as the operating stick was not moved, the fighter remained in its original state, it was originally a dive, and now it is still diving, so if you look down at the radar, it is very dangerous and it is easy to fall.
And the current fighters, even if they are in a dive state, as long as they release the operating stick, the fighter will be flattened.
In the most extreme case, if there is a loss of spatial awareness, release the lever.
The loss of the sense of space is one of the most terrible of pilots, and it has happened before that when a fighter plane is in flight, it treats the sea as a blue sky and plunges into it all at once.
The bright line on the radar screen was turning in circles, and finally, the target appeared!
"Twenty-three thousand meters, intercept the target." Qin Feng said.
At this time, the multi-pulse irradiator in front of the nose is also working at full power, looking for targets from the clutter on the sea surface, plus today's waves are not very large, the wave height is only half a meter, and the height of the Mirage F1 fighter is enough, so the target was finally found at 23 thousand meters.
Other indicators are not bad, this downward vision ability, as expected, is the same as Qin Feng was worried about, unqualified, twenty-three thousand meters, can already visually find the target, at this time, the radar has just intercepted the target!
Moreover, this is still on the surface of the sea!
Qin Feng's eyes withdrew from the radar screen, glanced outside, and then said, "Report, ask for an additional item, look up and down the land to search." ”
As soon as Qin Feng said this, Colonel Mido was stunned, and Colonel Mido said: "Now that we have completed the test flight mission, let's go back." ”
"Report, this is not difficult, we can carry out this test as long as we land behind." Qin Feng said: "The ability to search downwards has a lot to do with the reflection of clutter on the ground, if we only test it at sea, we will not be able to get satisfactory data, and we may have to test it again in the future." ”
The Chinese Air Force is here to test the Mirage 2000, it can be said that Dassault must respond to requests, for the radar test, I thought it could end perfectly, who knows, the other party has put forward a new request, this request, Colonel Mido can not refuse, easy to do.
