多雷达航迹的镶拼处理

The Mosaic Processing of Multi-radar Tracks

本文主要讨论如何对航管中心的多雷达航迹相关进行分析处理,其方法将多部不同程式雷达覆盖的管制区域,分成若干小格.根据雷达布局情况,来确定在某格中雷达航迹的优先顺序,同时还引出和定义了嵌拼表,对应表、系统航迹表.当一架飞机航迹点进入某格内,按一组相关准则(位置、速度准则、高度和二次代码准则)进行的相关确认后,选择出高质量的系统航迹、新航迹或单雷达航迹.

This paper mainly treats of the analysis and processing of multi-radar track correlation in an ATC centre. The method is to divide the controlled areas covered by different radar sets into several checks. The order of priority of the radar tracks in the checks is determined in accordance with the radar layout and, in the meantime, the embedment table, the correspondence table and the system track table are drawn forth and defined. As an aircraft track appears as moving dots in a check, its high-quality system track, new track or single track can be selected after the correlation definition is made according to the correlation rules (position, speed rule, altitude and the secondary code rule).
