The Passive Location of Emitter based on Fuzzy Method. [Purpose] The use of passive observation station to achieve the precise location has been an important topic of monitoring the electromagnetic spectrum resources and the environment. In order to locate the emitter accurately, a new method called fuzzy method is presented in this papers. [Method]Based on the distribution of points of intersections that are figured out by the LOB (Lines of Bearing), the paper put forward a fuzzy method for the passive location of emitter based on membership function to achieve the location of emitter. We compared this method with Pages method using 100 sets experimental data through the Monte Carlo simulated experiment. [Results] The results showed that this method can effectively achieve the location of emitter, and improve the location accuracy. [Conclusions] The positioning precision of this algorithm is obviously superior to Pages algorithm.
