一篇music算法的文档，名字为基于均匀线阵的改进MUSIC算法(Algorithm is a music document, the name is based on uniform linear array MUSIC algorithm for improved)

单用户的虚警概率和检测概率的关系，程序正确，简单易懂，值得参考(Single-user relationship probability of false alarm and detection probability, the program is correct, easy to understand, it is also useful)

用MAtlab写的不错的运动目标检测的分析平台。 研究人员可借此学习在Matlab71上如何编写图形化界面的程序， 同时可以将自己的代码在平台上面运行，方面地查看运行的效果。(MAtlab written with a good moving target detection analysis platform. Researchers can learn how to prepare Matlab71 graphical interface procedures, also can be its own code of the platform above operation, Operation View regard to the effect.)
