Image Formation Algorithm for Wide-Coverage Spaceborne/Airborne Hybrid Bistatic SAR

摘要：

To efficiently realize high-precision imaging for spaceobrne/airborne hybrid bistatic SAR (SA-BSAR) in wide-coverage case, a space-variant range cell migration (RCM) compensation method, which is based on SA-BSAR’s two-dimensional space-variant RCM model, is proposed in this paper. In this method, Inverse Scaled Fourier Transform with variant scaling factors (ISFT-v) and block division technique are collaborated. Accordingly, a high precision and computationally efficient frequency-domain imaging algorithm based on this RCM compensation method is developed. The imaging algorithm is validated with wide-coverage point targets simulation.
