Abstract

The polarimetric DECOMPOSITION is one of the most important steps in SAR data processing and analyzing. Conventional DECOMPOSITION methods use polarimetric information only in a restricted number of polarization bases. This paper presents a new DECOMPOSITION method based on POLARIMETRIC SIGNATUREs. The proposed DECOMPOSITION includes two main steps: 1) selection of the reference POLARIMETRIC SIGNATUREs, and 2) Classification of the pixel's POLARIMETRIC SIGNATURE. The presented method was tested on the Radarsat-2 image in C band collected over San Francisco and the Pi-SAR image in L band collected over Niigata University in Japan. The proposed DECOMPOSITION was compared with Y4O, Y4R, Arii-NNED and Freeman DECOMPOSITION methods. According to the results of the suggested method, in urban areas especially in areas with a large orientation angle, it is clearly seen that the overestimation of the volume contribution has been reduced and the double-bounce contribution has been increased. In addition, the obtained power values of the proposed DECOMPOSITION are always positive; therefore, the problem of negative power value cannot be achieved.
