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！ (compressed sensing)

仿真SMI（DMI）算法性能，观察采样快拍数对波束图的影响，接收信号中不包含、包含信号功率逐渐加大对波束图的影响。(Simulation SMI (DMI) algorithm performance, the number of snapshots observed sampling effects on the beam diagram, the received signal does not contain, include the gradual increase in signal power diagram of the impact beam.)

PESQ measure: ------------- Usage of the PESQ objective measure is as follows: [pesq_mos]=pesq(cleanfile.wav,enhanced.wav) where cleanfile.wav contains the clean speech file and enhanced.wav contains the enhanced file.
