摘要
首先介绍了我们最近提出的一种ISAR自聚焦新方法AUTOCLEAN(AUTOfocus viaCLEAN),然后对其中的特征提取算法进行了深入研究。研究结果表明,用CLEAN作为特征提取算法是合适的。AUTOCLEAN不仅是一种稳健的ISAR自聚焦方法,而且还可以推广应用到聚束SAR、曲线SAR和机载双天线干涉SAR中的自聚焦处理。
In this paper, we first introduce our newly devised ISAR autofocus algrithm AUTO-CLEAN. Then the feature extraction step is further studied, and investigation results show that CLEAN isa good candidate. AUTOCLEAN is not only a robust ISAR autofocus tool. but also can be used for the au-tofocus of spotlight SAR, curvilinear SAR, and interferometric SAR with two antennas.
