Abstract

An innovative data-based motion compensation approach is proposed for the highresolution synthetic aperture radar (SAR). The main idea is to extract the displacements in line-of-sight direction and the range-dependent phase errors from raw data, based on an instantaneous Doppler rate estimate. The approach is implemented by a two-step process: (1) the correction of excessive range cell migration; (2) the compensation of range-dependent phase errors. Experimental results show that the proposed method is capable of producing high-resolution SAR imagery with a spatial resolution of 0.17 × 0.2 m2 (range × azimuth) in Ku band.
