Abstract

The main problems of detecting and imaging of moving targets with airborne synthetic aperture radar (SAR) are addressed. Novel methods are developed to estimate the two important parameters in imaging of moving targets -- the linear FM rate and Doppler frequency center of received echoes. There are extended Wigner-Ville distribution and Doppler frequency center estimation based on the WIgner-Ville distribution. So these parameters can be used to form synthetic aperture with respect to each moving object and produce high resolution image. Some estimated results and diagram of process are given.
