摘要
本文研究了一种用于冲激ＳＡＲ成像处理的算法——反向投影法，该算法不同于满足“远场、窄带”约束条件下的常规ＳＡＲ的频域成像算法。本文阐述了后向投影法基本原理，并对在运用后向投影法成像过程中所遇的一些特殊问题作了分析并提出了解决办法。最后，本文给出了计算机仿真结果，验证了反向投影法的有效性、正确性。
The Back Projection Algorithm adopted in the process of impulse SAR imaging is analyzed in this paper.The algorithm is different from that of conventional SAR imaging formation.Its basic theorem was presented,and some special factors concerning the quality of imaging,such as,sampling speed of A/D converter,azimuth accumulating angle,were analyzed.For improving the imaging quality,a method was provided.Finally,results of the computer simulation were given to demonstrate BP effective in impulse SAR imaging.
