Estimation of source motion from time delay and time compression measurements

Abstract

Expressions are derived for estimating the cross line-of-sight speed (CLSS) component of velocity from relative time compressions (RTC’s) and time delays. Theoretical expressions for the rms error in radial speed and CLSS are given and have been corroborated by simulation experiments. These expressions show the relative difficulty of estimating radial speed information as compared with CLSS.
