- 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,

- 正交匹配追踪(OMP)算法属于贪婪算法。而贪婪算法是一种不追求最优解,只希望得到较为满意解的方法。贪婪法一般可以快速得到满意的解,因为它省去了为找最优解要穷尽所有可能而必须耗费的大量时间。贪婪算法常以当前情况为基础作最优选择,而不考虑各种可能的整体情况,所以贪婪算法不要回溯。(Orthogonal matching pursuit (OMP) algorithm belongs to greedy algorithm. Greedy algorithm is a method that does
