摘要：
Due to its advantages of lightweight, cost-effective and high resolution, the combination of frequency-modulated continuous-wave (FMCW) technology and circular scanning synthetic aperture radar (CSSAR) promise a bright future in the application of fast large-area imaging. In order to handle the CSSAR signal and consider the residual secondary phase error introduced by FMCW technique, a new imaging algorithm suitable for FMCW-CSSAR is proposed, and precise imaging is realized with range highly approximated and residual secondary phase errors fully compensated. Simulation results of point targets are given to prove the effectiveness of the proposed approach.
