摘要
讨论自相关多途时延估计方法．分析了自相关多途时延估计方法的估计精度，并将其与ＭＬＥ估计器进行了比较；并针对实际情况讨论了海面波动对多途时延的影响．用自相关法对一组海上试验的数据进行了处理，并对处理结果进行了分析．理论分析与实际数据处理表明，自相关法是工程中进行多途时延估计的较好方法．
The precision of multipath time delay estimation using auto correlation is analysed and compared to the performance of the maximum likelihood estimator (MLE).And also we discussed the influence of the rough surface on multipath time delay estimation.A group of ocean experimental data are processed using auto correlation method.The theoretical and experimental results indicate that auto correlation method is a good choice for multipath time delay estimation in engineering.
