说明: 压缩感知 正交匹配追踪一些人关心压缩感知与雷达成像,他们把稀疏表示放在最重要的地方,以为在雷达成像中成功实现压缩感知关键是稀疏表示;
事实上并不是如此。我们知道:压缩感知需要建立AX=B,且该方法具有较低的抑制信噪比能力;另外雷达成像的基础是雷达
信号与目标的相互作用,也就是电磁波与介质的相互作用,该相互作用是一个非常复杂的非线性问题,因此研究这个问题与
压缩感知的关系才是解决雷达成像问题的关键点所在。从另外一个角度来看,雷达成像中惯用的方法是匹配滤波,它之所以
能够处理低信噪比的问题,是因为它利用了回波数据的冗余信息。也就是目前雷达成像算法之所以成功的关键是具有足够
多的冗余信息。现在,在雷达成像中使用压缩感知恰好是反其道而行之!
