雷达信号的MATLAB仿真常常是因为运算时间问题而失败，经过试验，在实际编程中，采用调用子函数方法就遇到该问题，为此，改为采用的查表法实现，有效解决了该问题。故将该源码上传供同行参考。-radar signal simulation of MATLAB because computing is often a matter of time and failure, after testing, the actual programming, using call Functions encountered on the way, in connection with the look-up table method to achieve, an effective solution of the problem.
