Abstract
In this paper, we designed a new two-stage algorithm to formulate accurately the focusing image with the highly squinted synthetic aperture radar. First of all is the general model of the squinted synthetic aperture radar (SAR) focusing a fixed area. After the echo data collection, the first stage of the algorithm is to establish the coarse image by performing the conventional range cell migration correction and azimuth matched filtering. In the second stage, the azimuth-variant was corrected and the motion compensation was carried to achieve a better image. A simulation experiment was given in the end.
