From 1938 to 1939, the United Kingdom developed the first batch of ASVMk II airborne sea search radars and AI airborne interception radars. Subsequently, the United Kingdom and the United States developed the H2S (10 cm) and H2X (3 cm) microwave bombing radars, which were put into use successively from 1942 to 1943.
From the mid-1950s to the 1960s, airborne radar adopted new technologies such as single pulse angle tracking, pulse compression and synthetic aperture, and its anti-interference ability, range, resolution and measurement accuracy improved significantly. With the improvement, the scope of application has also expanded. In addition to controlling artillery or bomb aiming, it can also guide air-to-air missiles or air-to-ground missiles. And radars such as weather, terrain following, and feature avoidance have appeared.
In the 1970s, digital electronic computers and pulse Doppler technology were applied in airborne radars, which improved the radar's information processing, ground (sea) surface clutter suppression and adaptive capabilities, and achieved greater results. Complete in-machine self-checking system and fault isolation device.
The Chinese People's Liberation Army began to equip airborne radars in the 1950s. In the 1960s, it independently designed and developed monopulse system airborne interception radars and bombing radars. In the 1970s, various systems and multifunctional airborne radars were developed.
