This article mainly described a bearings-only passive ranging method with IRST System. Since the Kalman method has disadvantages such as slow converging speed and low tracking accuracy. We applied a new method called particle filter with constraint between generations with the IRST system for the passive tracking. In this method, we update the distance by using the constraint between generations, and by using the new datas in particle filter, we can control degeneration of the particle. The simulation results shown that this method has faster converging speed and higher precision than existing ones, can be good for maneuvering target tracking and measuring target range.
