摘要
以水下航行体被动定位为背景,提出基于互相关函数的频域实现实时权函数估计广义相关法、三次相关法和互相关函数双谱法等三种时延估计器。
To locate of the underwater vehicle, several cross correlation function based time|delay estimators implemented in frequency domain including real time weighing function estimated generalized correlation estimator, thrice correlation estimator and cross correlation function bispectrum estimator are presented.
