Target recognition based on characteristic polarizations, in the optics region

In this paper, characteristic polarizations are used to describe the stability properties of target's spatial polarization structure in optics region on the wideband polarimetric radar. On this basis, polarization features are extracted to classify four kinds of aircraft. Recognition results show that these features are insensitive to target's posture to a great extent and this method based on characteristic polarization is effective and feasible.
