说明：  Matlab做的关于三角波，正弦波，方波的FFT算法，可以分析方波信号、三角波信号的频谱以及采样点数、采样频率对频谱分辨率的影响。(Matlab to do on the triangle wave, sine wave, square wave of the FFT algorithm, can be analyzed square-wave signal, triangular wave signal of the spectrum as well as the sampling points, the sampling frequency affect the resolution of the spectrum.)

由于小波函数没有显示表达，此程序通过数值方法将其表示出来(wavelet function)

说明：  Statistical Signal Processing

对一维线相控阵和二维平面相控阵天线用matlab仿真出来，展示相控阵的方向改变能力和多波束形成能力。(One dimensional linear phased array and two-dimensional phased array antenna with matlab simulation, show the change of direction of the phased array and multi-beam forming ability.)
