On the Measurement of Range and its Time-Derivatives in LFMCW Radar

Abstract

This paper examines the simultaneous measurement of range and its time-derivatives in Linear Frequency Modulated Continuous Wave (LFMCW) radar. A signal model is developed to highlight the influence of velocity modulations on estimating higher range derivatives. Experimental results demonstrate the validity of the signal model and the merits of simultaneously estimating range and its derivatives such as acceleration and jerk.
