幅度和差测角和相位和差测角的MATLAB仿真程序，相位和差测角采用阵列天线，信号采用窄带点频信号，通过直接使用配相和波束形成后的表达式来仿真，幅度和差测角和相位测角类似，只是多了用sinc信号仿真(The difference between the measured amplitude and phase angle and the angle of deviation between the measured and MATLAB simulation program, and the difference between the phase angle measurement using an array antenna, the signal point using narrowband frequency signals, by directly using the distribution phase and beamforming expression after simulation, the amplitude and the difference Similar goniometer and phase angle measurement, but more with the sinc signal simulation)

本程序是关于预测函数的几个程序，包括阶跃输入以及在干扰情况下的系统影响，控制效果良好，自己可以其中的参数！(This procedure is about the predictive function of several procedures, including the step input, as well as the interference situation in the system under the impact of control works well, the parameters in which they can!)
