Abstract

The effects of residual cubic phase error induced by Chirp Scaling algorithm on SAR image qualities are analyzed, and a SC-Chirp Scaling imaging algorithm for high resolution spaceborne SAR based on nonlinear FM filter is proposed in this paper. Squint equivalent range model is used, and a nonlinear FM filter method is applied to achieve cubic phase error correction in the algorithm. Computer simulation results illustrate the algorithm having the capability to acquire evident improvement of high resolution spaceborne SAR image qualities.
