说明：  SAR雷达模拟的PPT，讲述SAR雷达回波模拟的具体原理，实现方法，和仿真结果(SAR)

this is code for Distance Regularized Level Set Evolution and Its Application to Image Segmentation paper. I used this code and it was correct and have true answers.

保铮写的雷达图像经典著作，搞雷达图像研究必备(radar image)

这个利用matlab软件话三维连续系统的相图的程序，比如lorgenzeq系统的相图，也可以画超混沌的相图，(The matlab software using three-dimensional continuous system, then the phase diagram of the procedure, such as lorgenzeq system phase diagram, can also draw hyperchaos the phase diagram,)

DOA 中的caponBF， 阵列信号处理的一个基本问题就是确定同时处在空间某一区域内的多个感兴趣的空间信号的方向或位置，即实现信号的分辨和定位，这也就是雷达、声纳最重要的任务之一，为了解决这一基本问题，主要采用常规波束形成法。(DOA of caponBF, a fundamental problem in array signal processing is to determine in space at the same time more interested in a particular area of space signal direction or position, namely the realization of signal resolution and positioning, which is one of the most important task in radar, sonar, in order to solve the basic problem, mainly using the conventional beam-forming method.)
