A method of time delay estimation by two times spectral analysis, where the time delay is the time interval between peaks of spectrum of the cross power spectral density, is proposed in the paper. It can be used to estimate time delay of not only single target but also multi-target without unwrap.

本文提出了两次谱分析时延估计方法，即将互功率谱函数再次进行谱估计，二次谱峰值位置间距即为时延估计，这种方法既能够估计单目标时延，又能够估计多目标时延，并且不用相位解绕。
