用模糊函数法进行时频分析，特别好的程序，本人写论文用到的。(Ambiguity function method using time-frequency analysis, in particular, a good program, I used to write papers.)

方位估计是阵列信号处理的重要内容，使用单个矢量传感器估计信号方位近几年才发展起来(DOA estimation array signal processing is an important aspect of using a single vector-sensor estimate signal directions only in recent years developed)
