The Algorithm of Passive Location of Emitter Based on LOB

[Purpos] The use of passive observation station to achieve precise location of an emitter is the precondition of electronic countermeasures and fire destruction in the modern information war. [Method] This paper dissects several modern typical location methods which are based on LOB. On this basis, the paper puts forward fusion-iteration location algorithm, and makes Monte Carlo simulated experiment to compare with Pages-Zamora method which is used by FCC and probabilistic location method. [Results] Experimental results show that CEP of fusion-iteration location algorithm is the minimum one. [Conclusions] Pages-Zamora method is a typical location method and fusion-iteration location algorithm shows higher precision than Pages-Zamora, so fusion-iteration algorithm is an effective passive location method.
