摘　　要：分布式雷达组网的航迹关联不仅与网内各雷达的性能有关,而且与目标的相对位置有关。本文提出一种新的雷达组网航迹关联方法,该方法在综合网内各雷达性能的基础上,将组网雷达定位精度几何稀释模型引入航迹关联算法当中。根据各雷达对观测同一目标定位精度的差异为参考,给出一种新的航迹关联门限阈值选择算法。本文介绍了航迹关联阈值的计算过程,并利用该方法对真实航迹数据进行了仿真。Track correlation of Distributed Radar Network is not only related to the performance of the radar, but also to the relative location of a target. A new method for radar netting track correlation is presented. On basis of synthesizing performance of each radar within network, this method is to introduce the network radar geometric dilu- tion of precision in the track correlation algorithm. Taking the difference of positioning accuracy for different radar observing the same target as reference, the new track correlation threshold selection method is presented. The calculation of this method is described and the simulation of real track data is conducted.
