An Improved nonlinear chirp scaling Algorithm with Capability Motion Compensation for One-Stationary BiSAR

摘要：

This paper deals with the imaging problem of one stationary bistatic Synthetic aperture radar (BiSAR) with motion error.Since a motion error is the main phase error source in the aircraft SAR, the motion errors have to properly be compensated during the SAR image reconstruction. The nonlinear chirp scaling (NLCS) algorithm is one of the typical algorithms in the practical radar system. An improved NLCS algorithm which can compensate motion error for One-Stationary BiSAR is proposed. Specially, the proposed method is based on the constant acceleration movement and the sub-aperture technique.
