摘要 为了构建实用性强、自动化程度高的SAR图像目标鉴别过程,提出了一种目标鉴别新方案,包括鉴别的框架及相应的算法.在系统层面上,为了更有效、更可靠地剔除杂波虚警,方案中提出了基于特征提取鉴别方法和基于编队提取"序贯"结合的整体框架;在算法层面上,首先进行了鉴别特征的提取,包括已有特征的提取以及三个新特征的提出;其次在特征选择阶段,提出了一种基于遗传算法的特征选择算法,该算法对于特征优劣的评价更全面.然后,为了提高鉴别器的精度,设计了目标鉴别的加权二次距离鉴别器,提高了鉴别的性能.最后,为了更有效地剔除杂波虚警,给出了基于目标编队知识进行进一步杂波虚警剔除的方法.实测数据的实验结果证明了所提方案的有效性.
