Quantitative comparison between PW-PSM and PW-TSM Doppler systems

Abstract

A simulation-based quantitative comparison between pulsed-wave (PW) Doppler systems using the conventional phase-shift measurement (PSM) technique and the newer time-shift measurement (TSM) technique is presented. A PSM system applying an autocorrelator is compared with a TSM system. The performances of the two systems are compared from zero velocity up to a velocity where detection is no longer possible. With increasing velocity, the coherence between consecutive received signals decreases which eventually results in detection of random peaks with TSM. This is illustrated by showing the relative amount of incorrect detections as a function of velocity. Also, the variance (PW-PSM) and the cross-correlation coefficient (PW-TSM) are found
