Among various modern reconnaissance methods, radar reconnaissance is most used. There are radar everywhere in the sky, ground, sea, land and air. Radar is a foreign language, an English abbreviation transliteration, which means radio positioning.
This use of the reflex characteristics of the wireless radio waves to detect aircraft, missiles, ships, vehicles, weapons, bridges, residents, etc. Essence The transmitted radio waves are the same as the wave frequency, which is the fixed goal; the difference is the active goal. The frequency of return waves is higher than the transmitting frequency, which is the target to the radar side; the low is the opposite, indicating that the target is away from the radar. The faster the target movement, the greater the frequency change. This is the general principle of radar detection.
It said that the radar was first invented by Germans! Around 1933, the first practical air defense alert radar was successfully developed by German scientists.
But the German Air Force leader Gorin was stolen because the technology was stolen, which was a great disaster to the German Air Force. All technical materials are destroyed, deposited, and all the research work stopped. Instead, Britain and the United States have stepped up research under strict confidential conditions. In 1936, British scientist Watt developed a successful and practical air defense radar. In 1938, Britain and the United States also created airborne search radar and carrier -based early warning radar. Germany learned of the news and started to study again, and it has lagged behind others for 5-6 years.
The actual application of radar began in the British and German air combat in World War II. Germany concentrated 2400 aircraft, including 1480 bombers and air strikes in the UK. There are only 1,300 aircraft in the UK, only 700 for air defense operations, and the power is far away.
, Britain, with the help of radar, did not wait for the German aircraft to fly to the British island, and know how many batch of batch of planes hit, and then sent fighters to strike in favorable airspace. As a result, more than a month, Germany lost 1500 aircraft. The British Air Force, which is inferior to the German Air Force, has made great contributions.
The development to today’s radar has really become the “thousands of miles” on the battlefield. It can find thousands of miles away. It is almost restricted by various weather conditions of day and night, working all day and all weather. It can automatically search and track goals. It can identify the enemy and me through a pre -edited password. There are no other reconnaissance methods in the world to replace it.
The operating wavelength of the radar is between 10 meters and 1 mm, and the corresponding frequency is 30 mega to 300,000 trillion meters.
usually referred to the radar with a wavelength of 10 meters to 1 meter as ultra -short wave radar, and the radar below 1 meter is called microwave radar. There are two types of working methods: one is continuously transmitting electric waves, called continuous wave radar; the other type of radio waves are gaps, like a human pulse beating, called pulse radar.
The components of radar, generally include transmitters, antenna, receiver, antenna and receiving conversion switch, display, antenna control equipment and power equipment. The latest phase -controlling radar, there are hundreds of units in each antenna array, each unit can be a tiny but powerful transmitter and receiver. A radar can search, detect, track hundreds of hundreds of at the same time A goal. The radar design adopts the module method, and the civilian use of military use, which increases or reduces some functions. It only needs to change the module.
The military radar used for ground reconnaissance. Now there are:
battlefield reconnaissance radar, also called ground activity reconnaissance radar, mainly the army reconnaissance forces used to reconnaissance and monitor the ground Weapons, vehicles, personnel and low -altitude aircraft activities. The long -distance reconnaissance radar, the detection distance is 20-30 kilometers, weighs 60 kg, and is often installed on the vehicle. The mid -range detection range is between 10 to 18 kilometers. The detection range of close range is within 3 kilometers, and the weight is only two or three kilograms. Generally, it can work on the triangle frame.
The alert radar, configured in coastal, border defense and depth areas, some are located on the mountains, used to discover long -distance aircraft, missiles and ships to ensure that they have sufficient battle preparation time. This type of radar is far -near, divided into short -range, medium -range, long -range and ultra -long -range. The short range is 200 ~ 300, the medium range is 300 ~ 500 kilometers, the remote is 500 ~ 4000 kilometers, and the ultra -long -range is except 4,000 kilometers.
The hypertime distance radar, which is used to detect intercontinental missiles launched from the ground, some rail bombing weapons, and high -speed strategic bombers that can be used as ultra -low -air flights.
. It is different from the general radar that is low in operating frequency, between 2 and 60 MM. The radio waves emitted by it cannot penetrate the electrical departure layer, but jump forward between the ionization layer and the ground surface until the target jumps and reflects the receiver. It can provide more early warning time than ordinary radars. For ultrasound speed aircraft from three or four thousand kilometers, it can provide early warning time for more than 1 hour. Generally, radar can only have 10 minutes. Its weakness is that there are jumping blind spots, and regular microwave radars need to be made up.
The radar is a huge family. In addition to the general general radar, there are many special radars and radar specifically for improving a certain aspect. Dedicated radar such as guiding radar, guiding radar, artillery radar, mortar positioning radar. Radar that specializes in improving certain types of properties are: pulse compression radar that can improve distance resolution, single pulse radar that can improve angular resolution, and frequency distribution radar that can improve anti -interference capabilities.
The emergence of radar promotes the research and adoption of anti -radar technology. The easiest way is to adopt the method of deceiving radar. Hidden, providing false.
In 1982, before the Israeli Air Force attacked the Syrian missile base, two types of unmanned reconnaissance aircraft were launched with three devices.
is a metal reflector. Although the diameter is only 30 cm, but the power is large, the radar echo display will mistakenly think that the large -scale assault machine with a 35 -square -meter area comes. The other two are TV image cameras and radar spectrum data receivers. The Syrian army was deceived and falsely faked. The missile guided radar was turned on. As a result, not only did not investigate the situation of the army, but instead exposed its radar position, parameters, etc. to the army. This is an example of fake deception.
1991 During the Gulf War, the Iraqi army suffered a lot, but many tank cannons were preserved. Some army also escaped the bombing because the Iraqi army engaged in fake labor and fake tanks. , Fake aircraft, fake missile launch devices, and even a wall of the wall, making American satellites, air, and ground radar mistakenly think of it, guiding the aircraft and missiles to attack.
The really tanks and cannons were buried in the desert. 15 days after the air strikes of multi -national forces, 90 % of the aircraft and 99 % tanks in Iraq were not lost. After 33 days of air strikes, the Iraqi army still maintained a 70 % tank, 65 % of armored vehicles and cannons. Until the end of the war, Iraq’s shredded mortar missiles could be launched.
The radar reconnaissance and anti -radar reconnaissance, interference radar and radar anti -interference, anti -interference, have become a new tactical technology.
The countries are doing and what they want to do, how to improve and develop their own radar, and how to destroy and destroy the enemy’s radar. His ears are clear, making the enemy the deaf and blind, at least the back of the ear back. The world will continue to launch new radar, and new interference technologies will continue to come out.
