Abstract Fast and precise location method plays an important role in the data association and the target tracking for the passive sensor system. In order to solve the typical problem of the target location encountered in the netted passive sensor system, the vertical location method is proposed. Simulation results show that the vertical location method is an effective target location method, and its positioning error variance can achieve the Camer-Rao lower bound.
