摘　　要：利用多个外辐射源,单站可以对目标进行定位。文中研究了在多个外辐射源条件下,利用目标反射信号和外辐射源到接收站的直达信号的单站无源定位算法;并结合计算定位精度的几何稀释度的方法,定量分析了定位的误差,最后讨论了外辐射源数目会对定位精度产生的影响。计算机仿真验证了算法的有效性。The station of target can be confirmed using multi-emitters. In this paper,the single observer passive location method using the signals reflected from the target and the LOS in the condition of multi-emitters is researched . The location accuracy of this method can be analyzed by calculating the GDOP. At last,the influence of the number of multi-emitters is discussed . Its effectiveness is verified by the computer simulation.

关 键 词：外辐射源 到达时间差 几何稀释度 单站 无源定位
