Abstract:

Spaceborne spotlight SAR mode has advantages of relative wide coverage and high resolution. Moving target imaging using spaceborne SAR system is important in both civil and military applications. Current researches focus on ground and maritime target like vehicle and large ship, the topic about aeroplane is rear. Therefore, based on Chinese GF-3 spotlight SAR SLC data, a new moving aeroplane imaging method is proposed. the moving target signal model in spotlight SAR SLC is deduced, the residual range migration and azimuth quadratic phase are then analyzed. it turns out that the residual range cell migration and quadratic phase relate to the relative speed. then, the moving aeroplane can be focused iteratively via tuning the relative speed parameter. The GF-3 spotlight SAR data of a non-cooperative aeroplane is used to validate proposed method.
