摘要
首先建立了机载双基地SAR的信号模型,然后简要描述了RD算法以及波数域算法的基本成像原理和算法流程,最后基于双基地SAR的信号模型运用RD算法及波数域算法对点目标及面目标进行成像,并分析比较了在正侧式飞行模式下用两种成像算法的优缺点。
The signal model of airborne bistatic SAR is established. The basic imaging principles and the algorithm flows of the RD algorithm and the omega-k algorithm are briefly described. Based on the signal model, the point targets and the area targets are imaged through the RD and the omega-k algorithms. The strong points and shortcomings of these two algorithms are analyzed with boresight flight patterns.
