多被动传感器系统航迹融合原理开发多被动传感器系统以其隐蔽特性得到重视，然而缺乏针对其独有，特性的航迹融合法。本文分析了其信息接收特性和信息分布特性，在此基础上提出了“参数+位置”航迹关联算法和以CEP为权因子的航迹融合算法，并以典型系统交叉和时差定位系统为例进行仿真，验证了此方法的有效性，为解决多被动传感航迹融合问题提供了新的途径。Multi-passive-sensor system draw much attention because of its hidden character,but the track fusion algorithma gainstits u niquep ropertyi sla ck.Thep orpertyo fin formaitonr eceivinga ndd istribuitonis st udied,andth e"signal parameter+location"track correlation algorithm and the weighted track fusion method with weight CEP are put forward.Two typical system cross bearing system and time-of-arrival location system are emulated.Finally theeffectivity of this method is proved.
