1938, the United States manufactured the earliest gun aiming radar SCR-268, which was used to control searchlights to illuminate targets at night and guide anti-aircraft guns to shoot at targets. 1943, the United States developed the first conical scanning automatic tracking microwave gun aiming radar SCR~584, which was used to control the anti-aircraft gun aiming and shooting. In the mid-1950s, gun sight radar was mostly used to control large and medium caliber anti-aircraft guns. After the mid-1950s, it turned to the development of gun aiming radar to control small caliber anti-aircraft guns. Since 1970s, monopulse small caliber antiaircraft gun aiming radar has been developed, such as Var 102 1 gun aiming radar in Swiss "air defense" system.

With the development of electronic technology, gun aiming radar will further adopt the system of searching while scanning and tracking, so as to realize multi-target tracking; Combine with laser, infrared and television to expand radar functions; Improve low-altitude tracking, anti-jamming and anti-radar missile destruction capabilities.
