摘要
本文推导了基于超宽带 LFM信号模型的SAR的后向投影(BP)成像算法,研究了距离向压缩数据在方位向聚焦的具体实现,讨论了距离向采样率对图像性能的影响,最后通过计算机仿真,验证了算法的有效性。
BP imaging algorithm of ultra-wideband LFM signal is deduced in this paper. The realization of azimuth focusing is researched after range compression. The effect of range sampling rate on azimuth focusing is discussed. The algorithm is validated by simulation results in the end.
