Passive multi-lateration system which is composed of passive sensors can realize monitor on the cooperative target on airport surface while it cannot monitor the non-cooperative ones.To achieve realtime and effective surveillance on different kinds of targets

the radiation resource is integrated into the passive multi-lateration system

which results in locating the target with utilizing the radiation source signal’s scattering.In addition

due to the existence of the radiation source

each receiver can employ the time difference of arrival between the direct wave and target scattering wave

which is simplified the coherence of the time references among the different stations of the multi-lateration system.The simulation results show that the proposed technique can locate multi-targets effectively.The proposed method is an effective location method for all kinds of surface targets.
