极坐标系下的航迹灰色区间关联算法

研究了雷达组网中时变系统偏差存在时的航迹关联问题。在分析时变偏差影响的基础上,从航迹的不确定区域着手,提出一种基于极坐标测量参数的航迹灰区域表示方法,并以此建立了区间灰数关联模型,实现了无需对系统误差配准的航迹关联配对。仿真结果表明,算法是有效的,并且具有较好的抗差性能。

Gray Track Correlation Algorithm Based on the Polar Coordinate Interval Numbers

The problem of track correlation in the presence of time-variable system bias in a radar network is researched in this paper.Staring from the track uncertainty,a method that a gray area can be directly expressed into several polar coordinate parameter interval numbers is proposed on the basis of the analysis for the impact from the bias.And a correlation model on gray interval numbers is established to realize the goal that two bias tracks can be related to each other without registration.Results of simulation show that,this algorithm is effective and has a good performance under worse circumstances.
