Singularity detection of TWR echoes based on correlation

Abstract

This paper introduces a modified algorithm of singularity detection based on modulus maxima for through-wall radar (TWR) targets detection. By tracking the wavelet transform modulus maxima (WTMM) at fine scales, singularities can be detected, and the important information of human target is also selected. According to the singularities of TWR A-scan signal, it can be commendably given prominence to the targets. Finally, singularity detection based on modulus maxima was successfully realized.
