基于双曲线模型的生物雷达二维定位算法
Two Dimensional Localization Algorithm of Bio-Radar Based on Hyperbolic Model
摘要
Abstract
At present, most targets detection algorithms in two dimensions is multi-channels bio-radar chose to locate targets by finding the intersection of some arcs, these algorithms may not intersecting those arcs into one point because of the inaccuracies from one of the channels. This paper presented a two-dimensional target localization algorithms based on hyperbolic model, it combined the hyperbolic determined by two of the channels and the arc determined by another channel to realize the two-dimensional localization of the target. The results of the free space and through wall experiment indicated the method could accurately determine the two-dimensional coordinates of the target in Cartesian coordinates, the average error between the two-dimensional coordinates and the actual position of the target was about 10 cm, which verified the correctness and validity of the algorithm. The algorithm is simple and reliable, and can provide effective guidance for actual search and rescue work.关键词
