相控阵天线中,对各个子阵的幅度加权不同达到降低旁瓣的目的，本程序是子阵加权（taylor）程序(The phased array antenna, for each sub array amplitude weighting of different reduce sidelobe purpose, this procedure is the subarray weighting (Taylor) program)

应用matlab，通过对原有图像去噪算法的改进，实现效果更好的图像去噪。(Application of matlab, the adoption of the original image denoising algorithm to achieve better image denoising effect.)

matlab写的二维天线仿真，可获得场图，功率图，包括DB和线性尺寸的。( This interactive MATLAB program is used to plot two-dimensional (2-D)polar.And The program can plot any of the following: 1. Field pattern (linear scale) 2. Power pattern (linear scale) 3. Power pattern (in dB))

It will ask for input the bit stream then generate pseudorandom bit sequence, finally give output as direct sequence spread spectrum
