Abstract :
The target depolarization characteristic is investigated based on the wideband polarization radar system. Ellipse parameters are adopted to describe target polarization characteristic in optics region. Considering target posture effect on polarimetry in the wideband case, a multi-dimensional feature space is constructed. On this basis, recognition experiments on five kinds of aircrafts are made and results show that the recognition method presented is effective and feasible
