Abstract :
Recently, as the rapid growing use of dual polarization spaceborne SAR data for ship detection, it seems necessary in practice for us to find a favorable detection algorithm, however, which is still scarce in literatures. In this paper, based on the application of the whitening filter, we proposed to design a dual polarization CFAR (Constant False Alarms Rate) detection method for ship detection, with the verification of its CFAR property. Preliminary detection results of real Envisat/ASAR Alternating Polarization (AP) mode data were shown in the last section to validate the detection method.
