Performance Analysis of Time-Delay Estimation Systems

Abstract

This study deals with the problem of passive time delay estimation. The focus is on systems employing wideband signals and/or arrays of very widely separated receivers. A modified (improved) version of the Ziv-Zakai lower bound (ZZLB) is used to analyze the effect of additive noise and signal ambiguities on the attainable mean square estimation errors. When the lower bound is plotted as a function of signal-to-noise ratio (SNR) one observes two distinct threshold phenomena dividing the SNR domain into three disjointed segments: at high SNR at moderate SNR and at low SNR.
