Comparison of early warning aircraft of military countries, what is the current level of China s ear

It can be said that it is the first in the world, and only Chinese AWACS aircraft in the world use phased array radar scanning. Other countries are a generation behind China in terms of mechanical rotary radar scanning technology. Neither the United States nor China can compare.

The KJ 2000 has a detection range of 120 ° per phased array antenna and a maximum detection range of 470 km against air targets. The aircraft's radar system can simultaneously track 60,100 air targets (including low-altitude targets and cruise missiles) and provide tactical guidance to 10 aircraft of the Air Force.

Active phased array uninterrupted early warning, first-class technology, average radar, and inferior aircraft.

Advanced level, the radar is good, but the aircraft performance is not very good.

AWACS stands for Airborne Warning and Control System

"Using its own radar to guide fighters to attack long-range air-to-air missiles out of line of sight" is not a proper job, and intercepting incoming cruise missiles is reasonable, but intercepting fighters is mentally ill.

The command function of AWACS is even more important than the early warning function, is it stupid for the commander to personally go into battle with the enemy?

In the Red Flag exercises of the US military, dozens of planes often start fighting at the same time, and without the early warning planes to command the overall situation with the Eye of God, the planes will easily be attacked by a sneak attack in the melee, or they will not be able to play a good coordination.

During the Gulf War, early warning planes commanded 90,000 sorties (a total of only 10,000 sorties), that is, 80 percent of the planes were commanded by early warning planes.

In anticipation, in 82 percent of the air combat records of the Gulf War, early warning planes discovered targets earlier than fighter planes. On average, when the AWACS aircraft discovered the target, the target was still more than 130 kilometers away from its own fighters.

On average, fighter jets find targets at 78 kilometers and launch missiles at a distance of 18 kilometers.

When the E-3A AWACS aircraft was first introduced, the US Air Force tests showed that it would take 60 - 100 aircraft to shoot down an AWACS aircraft.

And in real world combat, not a single AWACS aircraft has ever been shot down.

UAVs, F35 stealth fighters, also cannot replace AWACS.

As for saying that the J-20 penetrated the air patrol and shot down the early warning plane, it is not impossible, but the exchange ratio is definitely very high, and if the sacrifice of 5 J-20s can replace 1 early warning aircraft, it is time to burn incense.

Moreover, the side RCS of the stealth fighter is obviously larger than the front, so using two AWACS aircraft to open the distance can ensure that the side of the incoming fighter is irradiated and the detection distance is increased.

Although countries have never announced the distance at which AWACS will detect fifth-generation aircraft, it will certainly not be less than 100 kilometers, and it is likely to be more than 200 kilometers.

The E-2C's AN APS-145 UHF radar, which claims to be able to detect low-flying cruise missiles (-270 m² RCS), has now been upgraded to the E-2D.

AWACS aircraft mainly rely on their own strong battlefield situational awareness capabilities to detect incoming threats as soon as possible to ensure their own safety. When it is discovered that the enemy has air, ground, and sea forces that pose a threat to itself, the early warning aircraft can promptly guide its fighters or other air-ground forces to intercept them, or they can escape from the dangerous airspace as soon as possible. Once the enemy launches ground-to-air-to-air missiles, the early warning aircraft also has relatively advanced and perfect airborne self-defense electronic warfare devices, which can carry out soft damage (active and passive interference) against incoming ground-to-air missiles, thus ensuring their own safety.

The functions of early warning aircraft include: searching for and monitoring air or sea targets, directing and guiding their own aircraft to carry out combat missions; A combat aircraft integrating reconnaissance, communications, command, and control. AWACS aircraft are of considerable use in actual combat, greatly improving the efficiency of air combat, and air combat without AWACS aircraft is like losing an eye.

Early warning aircraft are mainly used on the battlefield for homeland security early warning, once an enemy plane invades, it can detect enemy aircraft at a long distance, leaving sufficient time to formulate a response strategy and achieve the effect of striking the enemy first. It is often used with fighter jets in actual combat as the eyes of fighter jets.

The early warning aircraft station is far away, he is the clairvoyant in the air, the brain center of air combat, and the air command post! The actual combat of the United States has shown that the early warning aircraft can increase the efficiency of air combat by 30 times, and the side with early warning aircraft in actual combat is also completely crushing the side without early warning aircraft, and the most important thing is that the early warning aircraft is an air mobile radar platform, and the maneuverability completely crushes any other radar platform, the layout is the most flexible, and the monitoring range is large, which is the role of the early warning aircraft!

AWACS purpose: an aircraft used to search for and monitor air or sea targets, command and guide its own aircraft to perform combat missions; The early warning aircraft is of great use in actual combat, and can improve the effectiveness of one's own fighters by more than 60 percent.

It is particularly useful, and in the process of air combat, it can intercept the opponent's fighters, and it can also predict some air dangers in advance, and it will not be sneak attacked.

Let's take a look at the main AWACS aircraft of the two countries.

China's Air Police 2000 while the American E-3 watchtower.

China's radar uses active phased array technology.

The United States, on the other hand, uses Doppler pulse radar.

It is true that in terms of technology, China is more advanced than the American AWACS aircraft.

Advantages of active phased array radars over other radars.

Phased array radar: A type of radar that is emerging and has many advantages.

1) The beam direction is flexible, which can achieve fast scanning without inertia and high data rate;

3) Large target capacity, which can monitor and track hundreds of targets in the airspace at the same time;

4) Strong adaptability to complex target environments;

5) Good anti-interference performance. All-solid-state phased array radars are highly reliable and can operate even if a small number of components fail.

There are also disadvantages: phased array radar equipment is complex, expensive, and has a limited beam scanning range, with a maximum scanning angle of 90° to 120°. When all-round monitoring is required, 3 or 4 antenna arrays need to be configured.

Each emitter of active phased array radar is equipped with a transmitting and receiving component, and each component can generate and receive electromagnetic waves by itself, so it has great advantages over passive phased array radar in terms of bandwidth, signal processing and redundancy design. Because of this, the cost of active phased array radar is expensive and the engineering is more difficult. However, active phased array radar has unique advantages in function and has a tendency to replace passive phased array radar.

All-electric sweep phased array and limited electric sweep phased array: all-electric swept phased array can also be called fixed phased array, that is, electric sweep is used in both azimuth and elevation angle, and the antenna array is fixed. Finite electric sweep phased array is a kind of hybrid design of the antenna, that is, the combination of more than two antenna technologies to obtain the desired effect, at first the phase sweep technology and the reflective surface antenna technology combined, its electric sweep angle is small, only a small number of radiation units are needed, so the cost and complexity of the equipment can be greatly reduced.

Nowadays, radars tend to be multi-functional, and often one radar inherits the characteristics of multiple types of radars, so the "radar type" becomes "radar function".

But comparing the data, you will find that although there are technical advantages in radar.

But there is no advantage in performance!!

The E-3 uses a Doppler pulse radar with a radius of more than 250 miles to detect high-altitude and low-speed aircraft (based on the radar horizon), a horizontal pulse wave (BTH) to detect aerial vehicles at medium and low altitudes (based on the radar horizon) at a range of 400 miles, and a sub-supervisory radar subsystem in the radar group to further identify and mark the target and the enemy's aircraft, and eliminate the clutter caused by ground objects.

And the Air Police 2000

Detection range: 470 km.

1 mile is equivalent to a kilometer.

Therefore, the Air Police 2000 does not have an advantage in performance.

China's most advanced early warning aircraft is released! The performance catches up with the American E-3, and the air warning capability is super strong!

China's latest AWACS 2000 is partially ahead of the United States in terms of technical data. PS: This is based on the data released earlier by the United States, which has been improving, and it is difficult to say what is going on now.

In addition, if the war can be decided by technical data, there is no need to fight, and the AWACS aircraft is not a direct combat force, and it needs to form a match with other combat platforms (information interaction, etc.). There is also no comparison between AWACS aircraft that did not participate in real combat and AWACS aircraft that the United States participated in wars. The key to the decisive victory of the war is the people, the people who use the **, not the ** itself.

This is not necessarily, because the US early warning aircraft have been developed for decades, and the Chinese and Americans have a long time in their homeland, and their technological accumulation is certainly not as good as that of the United States, but China's early warning aircraft uses electronic scanning, which is stronger than the mechanical scanning of the United States.

China's early warning aircraft technology is better than the United States, China's radar is a passive phased array radar, can 360 degrees without dead ends, while the United States E3 uses a mechanical scanning radar, than China's air police 2000 is a full generation behind! However, China's large early warning aircraft have a fatal shortcoming, that is, the pre-lame platform needs to rely heavily on imports, which also limits the number of early warning aircraft in China.

AWACS aircraft must be used in conjunction with fighters, and it also depends on the overall combat level, which in itself does not make much sense. It is said that China's early warning aircraft have some late-mover advantages, but there is probably a big gap between China's overall combat effectiveness and combat experience and that of the US military.

For AWACS aircraft, it is divided into two parts, one is the carrier aircraft, and the other is the radar electronic system. The carrier aircraft is of course the American Boeing series aircraft is quite good (especially the engine thrust is large, fuel consumption is low), and the radar electronic system, in addition to the United States, it belongs to Israel and China, although Russia is not bad, but for the miniaturization of the electronic system is still somewhat lacking, as China's famous early warning aircraft Air Police 2000 carrier aircraft Il-76 transport aircraft, its fuel consumption is notoriously large, but the Russian aircraft is also unambiguous, and the load is also very good. In general, the current American AWACS aircraft should be the best.

The American AWACS aircraft are the best in the world, followed by Israel.

An early warning aircraft, also known as an air command early warning aircraft, is an aircraft equipped with a long-range warning radar used to search for and monitor air or sea targets, and to direct and guide its own aircraft to carry out combat missions. A distinctive feature of most early warning aircraft is that there is a large "mushroom" on the back of the aircraft, which is the radome of the early warning radar.

The specifics are not clear, about 8 10 or so.

The US Air Force's E-3A "Watchtower" airborne early warning aircraft. The Navy's E-2C "Hawkeye" AWACS aircraft. E-8 "United Star" AWACS aircraft.

The E-3A "Watchtower" airborne early warning aircraft and the E-8 "United Star" early warning aircraft are both Boeing 707, which are modified from the four-engine long-range jet transport aircraft developed by the Boeing Company of the United States in the early days.
