Abstract
In this paper, a pairing algorithm of range information between multiple IR-UWB radar sensors is proposed to localize multiple targets. The IR-UWB radar sensors measure the distance of multiple targets anonymously, so that the range information of multiple sensors is needed to be paired to find a position of a specific target. The number of pairing cases increases with the increasing of the number of radars and targets. Algorithms to find the pair of the measured distances based on the cost function or segmentation of the received signal are proposed before, however, if the multiple targets are positioned in ambiguous positions which make multiple equally likeable fake locations besides the true position, the conventional algorithms fail to pair the distance information. To handle the problem, a new pairing algorithm of the distance information between the multiple IR-UWB radar sensors is proposed in this paper. The algorithm basically uses the information of variations in magnitude and distance invoked by a movement of a specific target. Using the proposed algorithm, the wrong pairing could be avoided with high probability. The performance of the proposed algorithm is proved by experiments using the two IR-UWB radar sensors.
