Abstract :
This paper addresses the problem of moving and nonstationary objects analysis in SAR images. A method, based on Matching Pursuit (MP) algorithm is proposed to decompose the SAR signal into a set of chirplets. Chirplets parameters can be related to physical characteristics of the SAR scene constituents and used to produce a multidimensional polarimetric bright point model of the object of an observed object
