目标信号为CW信号，阵型为八元阵，采用五路并联Notch滤波器进行相位差估计，完成水声定位功能。本程序是项目中的，已经经过调试和优化，可放心使用。(The target signal is CW signal, the array is eight yuan array, and the five phase parallel Notch filter is used for phase difference estimation to complete the underwater acoustic localization function. This program is in the project. It has been debugged and optimized, and it can be used safely.)
