Target localization by the method od joining intersections of the ellipses

Handheld UWB radar systems used for through wall target localization are usually equipped with one transmitting and two receiving antennas. Sometimes, the radar systems of that kind are not able to localize the target with required accuracy. In order to improve the precision of the target localization, cooperative positioning based on data fusion from two independent radar systems can be used. For this purpose, the novel method of the target localization referred to as the method of joining intersections of the ellipses is introduced in this paper. This method is based on the direct calculation method extended by a decision algorithm. The performance of the proposed method will be compared with the direct calculation method by using real data obtained by measurements by the UWB radar system.
