异地配置的雷达与电子支援措施航迹关联

Track Association of Radar and ESM at Different Sites

针对雷达与电子支援措施(Electronic Support Measures,ESM)异地配置的情况,提出了一种基于ESM虚定位点的异类传感器航迹关联算法。ESM属于无源传感器,只能获取角度信息而缺少距离信息。该算法首先基于雷达量测定义了ESM虚定位点,为ESM提供了目标的距离信息。然后利用ESM虚定位点与交叉定位点构造距离统计量,基于统计理论方法对雷达与ESM航迹是否关联进行判决。在不同的测量误差和目标数目环境下进行了仿真实验,结果表明,该算法能较好地实现雷达与ESM的航迹关联。

To improve the track association of radar and electronic support measures （ESM） at different sites, a track association algorithm of heterogeneous sensors based on ESM pseudo location point is proposed in this paper. ESM is a passive sensor, which can provide angle measurements but short of range measure- ments. To compensate the range information for ESM sensor, ESM pseudo location point is defined by utili- zing radar measurements. Constructing range statistics by combining ESM pseudo location point with cross location point, a new radar and ESM association algorithm based on statistical theory is proposed. Simulation is made with different errors and target number, and results show that the track association of radar and ESM can be finished effectively by using the proposed method.
