基于目标不变信息量的模糊航迹对准关联算法

探讨了在组网雷达存在系统误差情况时的目标航迹对准关联问题。通过将探测系统误差对目标航迹的影响表示为各目标航迹数据的旋转和平移,从而说明了目标之间的相对拓扑关系不受系统误差影响;由此提出了一种雷达组网模糊航迹对准关联算法,该算法通过提取包括目标间拓扑信息在内的各种不受系统误差影响的目标不变信息量,采用模糊信息处理理论来解决目标航迹的对准关联问题,从而较好地实现了误差配准前的准确航迹对准关联。

Fuzzy track alignment-correlation algorithm based on target invariable information

This paper researches the track correlation problem with measuring systematic errors in the radar network and analyzes that how do the systematic errors affect the detected tracks of targets theoretically, then expresses the effect caused by the systematic errors as some rotation and mass motion. So the relative topology relation between targets wouldn’t be affected by the systematic errors. On this basis, a fuzzy binary track alignment-correlation algorithm based on target topology is provided. The algorithm takes the target topology information into account synthetically and constructs the target topology fuzzy element set. Then the algorithm resolves the problem of target track alignment-correlation by using fuzzy information processing theory, and can correlate the target tracks with a good performance prior to registration.
