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)

Phase-shift keying (PSK) is a method of digital communication in which the phase of a transmitted signal is varied to convey information. There are several methods that can be used to accomplish PSK.
