| 摘要: |
| 针对传统的无源定位方法在城市、山区等非视距环境中参数测量误差较大进而影响定位精度的问题，提出了一种基于电磁地图的通信辐射源定位算法。首先通过在目标区域内部署分布式无线传感器网络采集电磁数据，利用感知节点采集的电磁数据构建目标区域的电磁地图，再通过构建的电磁地图作为先验信息用来确定辐射源的重点覆盖区域与潜在位置，最后通过改进的极大似然估计与序列二次规划得到辐射源的位置。仿真结果表明，在感知节点占比为1%的条件下，4 km×4 km区域内3个辐射源的定位平均误差小于60 m。 |

| Abstract: |
| In order to solve the problem that the traditional passive positioning method has a large parameter measurement error in non-line-of-sight environments such as urban and mountainous areas，which affects the positioning accuracy，a communication emitter localization algorithm based on electromagnetic map is proposed.Firstly，the electromagnetic data is collected by deploying a distributed wireless sensor network in the target area，the electromagnetic map of the target area is constructed by using the electromagnetic data collected by the sensing node，and then the constructed electromagnetic map is used as a priori information to determine the key coverage area and potential location of the radiation source，and finally the location of the radiation source is obtained through |
