摘要

距离多普勒(RD)算法以其较好的性能,在很长时期內都是SAR成像的标准算法,但传统RD算法的距离徙动采用逐点插值进行校正,运算量过大。文中提出了一种在平飞正侧视模式下改进的RD算法,无需插值,通过一次相位相乘校正距离徙动,运算量减少,与传统RD算法对比成像结果,有较好的聚焦效果,验证了改进算法的有效性。

Abstract

Range Doppler algorithm, due to its good performance, was considered as a standard of SAR imaging algorithm. However, the range cell migration of the traditional range Doppler algorithm based on point by point interpolation has a huge computational load. An improved range Doppler algorithm of bistatic side-looking SAR with parallel track was presented in this paper to deduce computational load using range cell migration corrected by once phase multiplication without interpolation. Compared with traditional range Doppler algorithm, the proposed algorithm has good focus effect, which verifies its effectiveness.
