  • A method of ground moving target detection based on subband and subaperture ATI image series is proposed. It exploits the wideband, large beamwidth and low frequency characteristics of UWB SAR to generate a series of subband and subaperture ATI images. These images corresponding to different centre frequencies and angle-views are combinded to detect a moving target and estimate its parameters. The proposed method in the paper has improvements over traditional ATI method. For detection, it removes blind velocity and can detect the moving target not only with range velocity, but also with azimuth velocity. Besides, it can estimate the unwrapped range velocity and azimuth velocity as well. The experiment based on UWB SAR half-real echo validates the method.
