机载双站合成孔径雷达Chirp Scaling成像算法

The Chirp Scaling Algorithm of Airborne Bistatic SAR Imaging

该文在分析机载双站SAR回波模型的基础上,结合常规单站SAR的Chirp scaling成像算法思想,推导出了双站SAR的Chirp scaling成像算法。对双站SAR的Chirp scaling成像算法进行了误差分析。最后通过仿真验证了算法的有效性。

The echo model of airborne bistatic SAR is analyzed in this paper. Based on the echo model and the chirp scaling algorithm of monostatic SAR imaging, the chirp scaling algorithm of bistatic SAR imaging is deduced, and its error is analyzed subsequently. Finally, it is proved to be correct by the simulation results,
