Target motion estimation via multi‐node forward scatter radar system

The focus of this study is on the estimation of the kinematic parameters of a moving target via a multiple‐input‐multiple output (MIMO) forward scatter radar (FSR) system. For this purpose, a crossing time‐based estimation technique is proposed that exploits the information on the time instants at which the target crosses the individual baselines of multiple FSR nodes to retrieve the target motion parameters. First the accuracy of such technique is investigated from a theoretical point of view through Monte Carlo simulations and then the effectiveness of the proposed approach is demonstrated by applying it to measured MIMO FSR data. Shown results prove the practical applicability of the proposed technique and demonstrate the potential of MIMO FSR configuration.
