Classification of Radar

Time：2020-05-19

There are many kinds of radar, and the classification method is very complicated. Usually military radar. It can usually be classified according to the purpose of the radar, such as early warning radar, search and warning radar, guidance and command radar, gun sight radar, altimetry radar, battlefield surveillance radar, airborne radar, radio altimetry radar, radar fuze, weather radar, navigation control radar, navigation radar, and collision avoidance and friend identification radar.

1. According to the classification of radar signal form, there are pulse radar, continuous wave radar, pulse compression radar and frequency agile radar.

2. According to the angular tracking method, there are monopulse radar, cone scanning radar and hidden cone scanning radar.

3. According to the parameter classification of target measurement, there are altimetry radar, two-coordinate radar, three-coordinate radar, friend-to-friend radar, multi-station radar, etc.

4. According to the technology and signal processing methods used by radar, there are coherent accumulation and non-coherent accumulation, moving target display, moving target detection, pulse Doppler radar, synthetic aperture radar, side-scanning side-tracking radar.

5. According to the classification of antenna scanning mode, it is divided into mechanical scanning radar, phased array radar and so on.

6. According to the radar frequency band, it can be divided into over-the-horizon radar, microwave radar, millimeter wave radar and laser radar.

Among them, phased array radar, also known as phased array radar, is a kind of radar that changes the beam direction by changing the phase of the radar wave. Because the beam is controlled electronically instead of the traditional mechanical rotating antenna surface, it is also called electronic scanning. Radar phased array technology has appeared as early as the late 1930 s. In 1937, the United States first began this research work. However, it was not until the mid-1950s that two practical shipborne phased array radars were developed. In the 1980 s, phased array radar was further applied because of its unique advantages. In the new generation of medium and long-range air defense missile weapon systems that have been equipped and are being developed, multi-function phased array radar is mostly used, which has become an important symbol of the third generation of medium and long-range air defense missile weapon systems. Thus, the combat performance of the air defense missile weapon system is greatly improved. In the 21st century, with the continuous development of science and technology and the characteristics of modern warfare weapons, the manufacture and research of phased array radar will be on a higher level.
