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.
