Surveillance radar ascends to an altitude of several thousand meters relying on aerostat. It can detect the “low slow small” target by lookdown. Therefore, aerostat surveillance radar is often used as safeguard equipment for the city major activities. But the ground target of high-speed moving and the “low slow small” target are very similar, the
