Ground moving target detection for airborne radar using clutter doppler compensation and digital beamforming

A novel and efficient method is presented for ground moving target detection. Radar echo data is transformed from element space to beam space using spatial Discrete Fourier Transform (DFT).

Summary:A novel and efficient method is presented for ground moving target detection. Radar echo data is transformed from element space to beam space using spatial Discrete Fourier Transform (DFT). A motion compensation matrix is applied to the beam‐space radar data to compensate for the moving platform effects on the Doppler spectrum. The Doppler‐compensated clutter is then eliminated using digital filters in time domain. It is demonstrated by the simulation results that the performance of the proposed airborne moving target indication (AMTI) algorithm is comparable to that of the conventional MTI processing approaches used in the surface‐based radar with stationary platform.
