基于声程差的多通道广义相关时延估计及其DSP实现

Generalized multi-channel correlated time delay estimation based on path difference and DSP implementation

本文将基于声程差的广义相关法时延估计应用于六基元阵，同时成功地将中值滤波及可变门限算法用于相关峰的自动跟踪，为了提高精度，导出了新的内插公式。最后给出了时延估计的结果。

in this papert the generalized correlated time delay estimation method based on path difference is applied to a six-element array. Meanwhile, the median filter and variable threshold algorithm aresuccessfUlly used for the auto tracking of correlation peak, To improve the time delay precision, a newinterpolation formula is proposed. Illustrative simulation examples are also presented
