成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

可以计算一维光子晶体的透射特性和反射特性，用的是传输矩阵法(TMM one-dimensional crytal)

This is the generation code for direct spread spectrum using pseudo-random noises. it shows how to generate it and also is implemented bit error ratio and the checking of autocorrelation.
