基于多相结构的信道化接收机，合成孔径雷达（SAR)目标成像仿真，cordic算法的matlab仿真。( Channelized receiver based on multi-phase structure, Synthetic Aperture Radar (SAR) imaging simulation target, cordic matlab simulation algorithm.)

知道结构加速度时程曲线后的速度、位移积分。(Know the structure of acceleration versus time after the velocity and displacement points.)

单脉冲和差波束测角程序。 此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖(Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan)

高斯光束在传播过程中，焦点处的三维光强分布(3D intensity distribution)

本代码使用matlab工具实现了一幅图片的位面图提取，且实现了在某个位面上加密信息、恢复信息的功能。并给出三幅图片的运行结果展示。(This code uses the matlab tool to achieve a picture of the bit plane map extraction, and the realization of the encrypted information in a bit plane, the function recovery information. And gives the results of running three pictures show.)
