| Abstract: | 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. |
