Cramer-Rao Lower Bound of Localization of a Moving Target by a Dynamic Multistatic Radar

This paper investigates the estimation performance of the position and velocity of a single moving target by a multistatic radar. Unlike in previous studies where either the transmitter(s), the target, or the receiver(s) is/are stationary, in this research both the transmitter and the receivers are moving and performing localization of a moving target. While the transmitter is not synchronized with the receivers and its position and velocity is unknown, the target location and velocity are jointly estimated using both the back-scattered and direct-path measurements. It has been shown that the movement of the receivers improve the estimation performance in terms of the Cramer-Rao Lower Bound. However, the improvement highly depends on the geometry of the dynamic network.
