摘　　要：无源定位技术具有良好的隐蔽性,对于提高系统在电子战环境下的生存能力有着十分重要的意义。因而采用多传感器的无源定位技术在军事领域中有着广泛的应用。建立了仅利用有角度信息的多传感器无源定位模型,在测向时间同步的条件下,利用基于UKF的序贯滤波算法提高定位精度。仿真结果表明滤波算法有效。Passive location technology could increase the survivability of the system for its concealed working style. So multi-sensor passive location technique could be applied well in the military domain. In this paper, the mathematical model of position which only uses the angel information is presented, and after time synchronization, we use sequential filter based on UKF to make the error less. The simulation results show the filter is effective.
