摘要
文中给出一种在频域上精确测量波达时差的方法,并深入研究了该方法中下采样频率的选取与测量精度的关系这一关键问题,给出了一种有效的选取原则。与时域测量方案相比,该方案不仅简单易行,且更易获得更高精度的测量时差。
In this paper, a frequency domain time difference measurement with high precision is presented.The selection of the down sample frequency is the key for this method.Compared with time domain processing,the method proposed is easy to realize and efficiency easy to achieve.
