中文说明： 本程序的性能已经达到较高水平，供做算法研究人员参考，音频信号通过LM386放大，直线阵采用切比学夫加权控制主旁瓣比，使用起来非常方便，包含了阵列信号处理的常见算法。
English Description：
The performance of this program has reached a high level, for the reference of algorithm researchers. The audio signal is amplified by LM386, and the linear array uses Chebyshev weighting to control the main side lobe ratio. It is very convenient to use, including the common array signal processing algorithms.
