Localization methods of multi-targets for UWB radar sensor networks

Localization methods are proposed in ultra-wideband (UWB) radar sensor networks which have one transmitter and two receivers. Localization of multi-targets is required to match each target and the corresponding receiver. Two localization methods for multi-targets are proposed to match the targets. First, we propose a target matching method based on the energy (TMME) returned from targets. TMME is effective for targets which have a big difference in the physical size. Second, we propose a target matching method based on the kurtosis (TMMK), which is a measure of the peakness of the distribution. TMMK is effective for targets to move to different postures. Experiment results show the effectiveness of the proposed methods.
