  • Multipath time delay estimation is constrained by the width of the signal correlation function when using correlation method. This paper obtains a high resolution tune delay estimation by introducing Burg and Marple algorithm of the maximum entropy power spectrum estimation to non-resovable multipath time delay estimation. The principle, the performances and the results of computer simulation are given.
