计算OSNR的小程序，从光谱仪抓取光谱后，直接计算(Matlab program for OSNR caculation)

使用MySin函数生成一个幅值为3、频率为10Hz的正弦信号x(t)，其中dt分别为0.1s、0.08、0.05s、0.005s。绘出四个正弦信号波形及其单边幅值谱(Use MySin amplitude function generates a 3, a frequency of 10Hz sinusoidal signal x (t), where dt respectively 0.1s, 0.08,0.05s, 0.005s. Sinusoidal waveform and draw four-sided amplitude spectrum)

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)
