Bispectrum time delay estimating based on correlation

摘要: 提出了基于接收信号互相关数据的双谱时延估计新方法,为无源跟踪系统提供了一种高精度时延估计方法。实航数据处理结果表明,该方法时延估计误差只有广义互相关法的1/6。

Abstract: The novel bispectrum time delay estimating method based on correlation data of the signals received by an array is presented in this paper, the RMS error of time delay estimation of this method is about one sixth of the error generalized by correlation method.
