Abstract :
To obtain high resolution image for real beam scanning radar, angular superresolution is studied, and a two-step scheme is proposed in this paper. In the scheme, using the threshold determined by CFAR-OSTU, the real beam data is divided into two parts firstly, and then maximum likelihood deconvolution with different number of iterations is conducted on the two parts of data. At last, the superresolution image is obtained by combining the two parts of data.
