针对单水听器的时间反转镜，给出了时反结果。(For a single hydrophone time reversal mirror, given the anti results.)

说明：  用于对基于GOLD码的串行捕获算法，可以自定义信噪比，待捕获信号参数，代码分成搜索跟踪和捕获两部分，其中搜索的步长等参数也可以自定义，代码中acquiresignal.m部分为最终捕获相位展示的主程序。(For the serial acquisition algorithm based on GOLD code, we can customize the signal-to-noise ratio and the parameters of the signal to be captured. The code is divided into search part and capture part, The parameters such as search step can also be customized. Acquiresignal.m part is the main progress to output the results of the capture of phase.)
