摘要
为了充分利用机载雷达的运动平台优势,提高机载雷达的目标定位精度,机载雷达通过数据链与另外一部机载雷达进行通信,完成双机探测情报的互通,实现双机协同探测的数据级融合,提高对目标的定位精度。介绍了数据融合的处理方法,针对双机协同探测的场景,仿真了双机位置变化的情况下雷达数据融合可以达到的定位精度,最后通过仿真计算,分析了两架飞机运动过程中融合精度的变化。该分析方法可以用于对机载雷达数据融合进行效能评估。
In order to take full advantages of motion platform of airborne radars and improve the target location accuracy of airborne radar,one airborne radar can communicate to another airborne radar through data link to finish the detected intelligence interflow between two airborne radars,realizes the data fusion of two airborne radars cooperation detection and improves the location precision of targets.This paper introduces the treatment method of data fusion,for the scene of two airborne radars cooperation detection,simulates the location accuracy that radar data fusion can reach under the state that two airborne radars’positions change,finally analyzes the change of fusion accuracy during two airborne radars motion through simulative calculation.The analysis method can be used to perform the efficiency evaluation of data fusion for airborne radars.
