Abstract :
A novel method of two dimensional reconstructing of radar target under strong clutter background is presented for target recognition application. In this method, the wide-band FMCW technology and orthogonal polarization signal processing technology are used. A matrix computation based signal processing method is proposed to obtain radial range dimensional superresolution and to obtain each polarization scattering matrix (PSM) of the every strong scattering center of radar target. Then the relations between geometrical features of canonical scattering centers and the polarization descripter are established by using degraded PSM matching classification algorithm. The range profile with signs of polarization description is called two dimensional range-polarization imaging and it is helpful for target recognition
