Description
Application speci c algorithms for processing SAR data have been researched for many years, but a general theory is not well de ned. This paper presents a generalized way to look at SAR processing and uses the principles leared to develop an improved motion compensation method. The non-ideal motion of a SAR platform results in degraded image quality, but for known motion, corrections can be made. Traditional motion compensation requires a computationally costly interpolation step to correct translational motion greater than a single range bin. This paper presents an ef cient new motion compensation algorithm that corrects this range shift without interpolation. The new method is veri ed with simulated SAR data and data collected with the NuSAR.
