Aiming at the application of passive trackinn based on sensor array, a new passive trackinn usinn sensor array

based on particle filter was proposed. Firstly, the“fake points\" could be almost entirely and exactly deleted with the aids of the

sensor array at the expense of an additional sensor. Secondly, considered the fact that the measurements notten from each array

were independent in passive trackinn system, a novel sequential particle filter usinn sensor array with improved distribution was proposed. At last, in a simulation study we compared this approach a坛orithm with traditional trackinn methods. The simulation re-sups show that the proposed method can nreatly improve the state estimation precision of sensor array passive trackinn system.
