摘要
在后向投影(BP)算法的基础上,提出了一种快速后向投影(FBP)算法。以点目标和多点目标为例,将该算法应用于超宽带合成孔径雷达成像并与原始(BP)成像算法进行比较,仿真结果证明了该算法的快速性和有效性。
A fast back projection (FBP) algorithm is proposed based on back projection (BP) algorithm, and the imaging results of spot target and multi-spot targets are received by applying both FBP algorithm and BP algorithm to UWB SAR. Through comparing the results, the speediness and validity of the fast back projection algorithm are testified.
