According to Doppler theory, simulated echo signal comprise the corresponding Doppler Spectrum, then ocean current velocity can be simulated.
并根据模拟回波信号中包含有相应的多谱勒谱的信息，模拟了海流的流速。
The implementation contains two parts: one is changing the distribution of the current by controlling the length of transmission line to controlling echo direction of the patch;
其实现方法包含两部分：一是通过改变微带传输线长度进而改变电流分布来控制阵元贴片的回波方向；
