Abstract: In this paper, principles and methods of several time delay estimators, adaptive
phase estimator and adaptive linear enhancer and their application in delay estimation are
introduced in this paper. As an example of our time delay estimation in applications, orientate
and ranging model of three asymmetrical elements is very effective and typical. The
application flow chart of the adaptive phase estimator and ALE, as well as the simulation and
experimental results are also shown. In the experiments the adaptive method performance of
delay estimation is excellent.
