Wavelets Based Algorithm For Time-Delay Estimation With Doppler's Shift

摘要

Many modern technologies imitate the perfectly evolved biological system. One of the examples is radar which is designed according to the echo system of bat which emits a signal and receives the reflection and then identify and localize the bag. Various features of a target can be identified by matching the transmitted and received signals. One of the matching methods is the so called correlation processing. This paper will propose a fast algorithm for estimating the time delay and Doppler's shift which in turn determine the velocity and the distance of a target we are interested. The algorithm combines the idea of wavelets and the principle of correlation processing together and therefore shares the advantages of both.
