Chapter045 Beyond Visual Range Air Combat Confrontation (Part 1)
Wang Yu used the radar silent mode to start this assessment, but his opponent was obviously different.
Not long after entering the assessment airspace, Wang Yu heard a sharp alarm from his radar warning receiver.
Eileen simultaneously reported that the fighter plane's radar warning detected a new air threat.
But what is more interesting is that after the alarm sounded, Wang Yu did not hear the continuous and rapid "beep" sound made by the fighter plane due to being repeatedly scanned by the radar beam. Instead, it still maintained a frequency of about once every four seconds.
By.
Wang Yu immediately determined that this was his opponent in this air combat assessment.
The other party does not seem to be afraid of revealing its general position, and directly extends the radar's scanning range to the widest range, and also increases the coverage height to the maximum. It can fully scan the 160-degree area in front of it, plus the area from the ground to 12,000 meters.
Height.
It's just that radar scanning is a process. For such a large scanning area, it takes about four seconds to complete one round.
The opponent expanded the scanning area to such a large area, probably just to roughly locate it.
When the electromagnetic waves hit Wang Yu's fighter plane, the opponent can determine the latter's approximate position at this point in time.
Presumably the opponent will then adjust its course based on this position, and then switch the radar mode and pitch angle to speed up the scanning - the radar will further speed up the scanning in the general area where Wang Yu is located until a lock is established.
But fortunately, so far, the opponent should have accidentally discovered his position due to good luck during the first round of scanning. The result of large-area scanning is that it is difficult for radar to continuously track - the opponent does not know his specific location.
It is naturally impossible to further establish a lock on altitude and heading.
If the other party establishes a lock, Wang Yu will hear a more rapid alarm sound.
Thanks to the radar warning system, he can now respond based on the opponent's position.
A radar warning receiver is essentially a signal receiver. When a radar's electromagnetic beam scans a fighter aircraft, the receiver will automatically display information such as the direction of the beam and the model of the target radar on the warning screen.
.
Give a simple and easy-to-understand example.
You shine a strong flashlight randomly in the middle of the night. When you shine the light on a passerby, the other person yells "moron". This is because the radar warning receiver has issued an alarm that the aircraft is under new threat.
And if you keep shining the flashlight on him, the passers-by will curse and greet your ancestors one after another. This is when the radar warning receiver starts to remind the pilot that his aircraft is locked by the radar.
Well...
That’s pretty much it, you need to have a spirit of understanding.
The moment the alarm sounded, Wang Yu pressed the lever to the right and turned.
He saw the approximate position of his opponent on the radar warning system. At this time, he had no intention of attacking him and engaging in a shooting attack. He thought he needed a bigger advantage.
He now completely treats this as an actual battle, and if he can't defeat him, he will have to sacrifice himself. Not only will he sacrifice himself, but the weapons controller in the back seat will also die with him.
He now needs to take advantage of the fact that the opponent only knows the general position of his machine and has not had time to scan it carefully, so that the opponent loses the target. He only needs to buy a little time to let himself take more initiative.
The F-15E's radar warning system is a real-time display screen that can be updated synchronously with the enemy's radar scan. When there is a threat, this display is naturally clearer and more intuitive.
What Wang Yu has to do now is to position his opponent in the three o'clock/nine o'clock direction of his fighter plane.
There are many benefits to staying in your opponent's three o'clock or nine o'clock direction.
Of course, this thing is related to the working principle of Doppler radar, and it seems to be deliberately short of words...
Oh, no, it feels like turning a novel into a popular science book, that would be too serious.
So as long as you know, this will prevent the opponent's radar from detecting Wang Yu's fighter jet at this distance.
"Sir, the opponent is an F-15."
When Wang Yu turned according to the opponent's position, Liu Lingxin in the back row reminded Wang Yu.
Her screen can bring up the TEWS interface (tactical electronic warfare system interface, mainly radar warning display). In order to help Wang Yu find enemies during air combat, she has made preparations in advance, so when the radar warning receiver sounds,
She immediately saw the new "logo" that appeared on the screen.
A rhombus nested within a circle. The word "15" is written in the middle of the diamond, and above this word is a small arrow.
This symbol is also easy to understand. The circle represents a new target, the embedded diamond represents the current main source of threats, and the small arrow above represents that the radar source scanning the aircraft is an aerial threat.
As for the number, it represents the specific model of the threat.
The radar warning system can determine the radar beam of the target and identify what radar emitted this beam based on the database. For example, the word 15 now displayed on the screen means that the radar warning system has determined that the electromagnetic wave is emitted towards it.
AN/APG-63 radar, and this radar is used by F-15A/B/C/D.
If the character is SD, it means that this is the search radar of the "Buk" missile system. If it is CS, it means that it is discovered by the S-300 air defense missile search radar...
Again, as in the example just now, both a laser pointer and a flashlight can be used to shine light on people. When you shine a light on a passerby, the other person will know whether you are shining a light on him with a laser pointer or a flashlight...
In short, whether you are a pilot or a flying officer, you need to remember what these symbols represent.
So Liu Lingxin knew the opponent's fighter model the moment she saw the display.
"I noticed it too."
Wang Yu replied without any pause in his hand movements: "So this is a battle of the same aircraft type. It looks like it's an F-15C. Well, we still have an advantage."
Obviously, the focus of Liu Lingxin's words is not here.
She immediately said: "As far as I know, none of the new recruits participating in elite internships at the base fly F-15."
When she said this, she shook her head like a rattle, even though Wang Yu couldn't see her movement at all now.
Wang Yu couldn't help but was stunned for a short time: "What?"
Liu Lingxin explained thoughtfully: "That is to say, the opponent on this F-15 is not a newcomer."
Wang Yu frowned when he heard this.
There are early warning aircraft monitoring the airspace, so it must not be an emergency, so it means that your opponent has temporarily changed.
Is this part of the assessment?
How pilots respond to emergencies.
However, Wang Yu shook his head slightly after a moment. It didn't matter who the opponent was and what kind of fighter he was flying. He just needed to meet the opponent normally and complete the assessment based on the current situation.
"Dear, when you get close to within sight, I will help you observe the other person's identity."
Eileen said this, which made Wang Yu feel relieved.
Seeing that the "15" on the radar warning moved from the twelve o'clock direction to the nine o'clock direction, Wang Yu adjusted the attitude of the fighter plane and tilted it slightly to the left, allowing the fighter plane to continuously fine-tune, keeping the opponent's position always in his own direction.
Nine o'clock.
The opponent is still scanning this airspace.
The Sanjiu maneuver is aimed at radar systems that rely extremely on the Doppler principle. For example, the opponent's AN/APG-63 is such a radar. When the distance is long, the ability to resist clutter is very poor. Faced with these Sanjiu maneuvers,
Mobile enemy aircraft are difficult to effectively detect.
The opponent will definitely not be able to accurately capture the position of Wang Yu's fighter jet.
But Wang Yu was still flying while paying attention to the radar warning screen and his own position.
Until the opponent's radar threat marker disappears from the screen.
This means that he has flown out of the opponent's detection range, and there is a large angle between him and the opponent.
Then Wang Yu understood that it was time for him to fight back.
He raised his hand and made a gesture to Liu Lingxin in the back seat.
Liu Lingxin nodded and sat upright.
The F-15E began to turn and pointed its nose towards the general direction of the target. Then, Wang Yu suddenly pushed full afterburner.
The fighter plane accelerated with a roar.
Taking advantage of the opportunity when the enemy loses his target, Wang Yu needs to quickly close the distance between the two sides.
After a period of acceleration, Wang Yu clicked a button to release the silent mode of the radar.
The fighter jets began to scan the opponent's area at full power.
