基于满意度门限检测的多雷达航迹对提取研究

针对多部雷达航迹对提取问题，首先提出了门限法，通过设定多个参数的门限，依据相关准则判断下一时刻的点是否选人该门限内，剔除野点后对单部雷达的观测数据建立航迹。进一步提出航迹在某时间段相交的判别准则，找出了各雷达站观测到的有相交时间段的航迹；对应多个有相交段的航迹，采用了线性插值的方法进行时间配准，让不同雷达表示同一目标位置的时刻集合扩大为一致；在此基础上，按照航迹相关准则抽取了表示同一目标的航迹对。仿真结果验证了算法的有效性。

Study on Track Extracting of Multi-radar Based on Threshold Checking of Satisfactory Degree

In order to extract the track of several radars,a method of multi-thresholds was given firstly.The method sets up several thresholds of those parameters,and judges whether the spots of the following moment cross these thresholds according to the related criterion.After getting rid of the field sites,each radar's track was built.Futhermore,another criterion which could judge whether those tracks intersect at some time was given,and so those tracks have intersect sections was finded.Corresponding to these int...
