中文摘要：

由被动传感器组成的无源多点定位系统可以实现对机场场面合作目标进行监视，而无法监视非合作目标。为实现对机场场面各类目标的同时有效监视，在无源多点定位系统中引入辐射源，使该系统可以利用目标对辐射源信号的散射实现对各类目标定位。另外，由于系统中辐射源的存在，各个接收传感器可利用辐射源的直达波与目标散射波之间时间差进行定位，避免各站间的时间基准统一问题，定位精度更高。实验结果表明：提出的方法可以有效地对场面多个目标进行定位，是一种有效的场面各类目标定位方法。

英文摘要：

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 reahime and effective surveillance on different kinds of targets, the radiation resource is integrated into the passive multilateration 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 muhi-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.
