摘要
基于天球坐标系的异型传感器量测数据分维融合方法是将三坐标雷达的量测分解为天球坐标与地心距离2部分,并在天球坐标系下对三坐标雷达和两坐标雷达的量测进行相关和融合处理,而后将系统航迹的天球坐标与三坐标雷达分解的地心距离联合,得出在大地直角坐标中的系统航迹的对空情报雷达网数据分维融合处理方法。仿真试验显示,该方法能够达到良好的位置关联概率和融合效果。
The fusion method based on celestial coordinate system divides the radar measurement into celestial coordinate and geocentric distance, and associates the data of the 2D radar and 3D radar under the celestial sphere coordinate system. Link of the celestial coordinate system and the centrifugal distance of system track can get the system track under Cartesian coordinate. Simulation showed the method has good position associated probability and fusion effect.
