Classification of Radar

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

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

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.
