Estimating Target Position and Tracking using Range only measurements in Multistatic Radar

Abstract

In the current proliferation of radar systems monostatic radars are replaced by multistatic radars due toenhanced coverage area, improved detection and tracking performance. As multiple transmitters are involved in the system, the received signal consists of a multicomponent form of the transmitted signal. At the receiver the multicomponent signals are separated to mono component signals which is the delayed version of the transmitted waveform. In this work the multistatic radar system is analyzed in terms of signal modelling and coverage area. The received multicomponent signals are separated and the range only target measurements are estimated in polar coordinates. The polar coordinate measurements are converted to Cartesian coordinates as the target models are presented by Cartesian points through unbiased coordinate conversion. Then the tracking performance is evaluated for velocity and acceleration models where extended Kalman filter is implemented for the nonlinear state estimation. The coverage area, signal separation and the tracking performances are verified through simulations.
