Abstract

Abstract:

In order to extend the swath of the SAR (Synthetic Aperture Radar) image to match the scene, the missile-borne ScanSAR wide-swath mode is studied in this paper. Firstly, the geometric model and the range equation are built, secondly the spatial variation of the linear range cell migration and the Doppler centroid are analyzed, thirdly the modified Range-Doppler algorithm and its computation load are analyzed, and lastly the geometric correction expressions are deduced. Simulation shows the effectiveness of the imaging mode and algorithms proposed.

Key words: missile-borne SAR, scan SAR, wide-swath, range-Doppler algorithm, geometric correction
