Abstract
Aiming at the problem that the clutter generated by the rotating target such as helicopter and propeller aircraft is difficult to suppress in the radar echo signal of the airport area.A method of processing radar echo data based on fast time constant CFAR is proposed in this paper.Firstly,the time frequency characteristics of clutter and weather radar echo signal generated by rotating target are analyzed.Then,the radar echo data is carried out in a fast and slow time,and the constant false alarm rate is processed in the fast time dimension,and the peak of the clutter pulse is eliminated,and the distance-Doppler field is obtained.Finally,interpolation of the missing parts in the data of the distance-Doppler domain is calculated and the inhibition effect is compared.The simulation results show that the proposed method can suppress the wideband clutter generated by the rotating target.关键词
