What is the development trend of radar?

Radar (radio detection and ranging) refers to radio search and ranging. It is a kind of equipment that uses various radio positioning methods to detect and identify various targets and determine target coordinates and other information. In modern military and production, the role of radar is becoming more and more important, especially in the "British" air battle between the British Air Force and the Nazi German Air Force in World War II, which makes the importance of radar very obvious. Radar consists of antenna system, transmitter, receiver, anti-jamming equipment, display, signal processor and power supply. Among them, antenna is one of the key technologies for radar to achieve large airspace, multi-function and multi-target; Signal processor is one of the core components of multifunctional radar.

There are many kinds of radars, which can be classified in many ways:

(1) can be divided into active radar, semi-active radar and passive radar according to the positioning mode.

(2) According to the installation position, it can be divided into: ground radar, ship-borne radar, aerial radar, satellite radar, etc.

(3) According to the radiation type, it can be divided into pulse radar and continuous wave radar.

(4) According to the work, it can be divided into long wave bands: meter wave radar, decimeter wave radar, centimeter wave radar and other bands.

(5) It can be divided into: target detection radar, reconnaissance radar, weapon control radar, flight support radar, weather radar, navigation radar, etc.
