中文摘要：

本文针对高频地波雷达双频信息融合的特点，提出威力范围分区混合式融合跟踪方法，将探测区域划分为有一定交叉过渡带的远、近2个分区，远区采用点迹融合，近区进行单频跟踪，最后对2个分区处理输出的航迹进行航迹融合形成系统航迹．分区混合式融合很好的适应了高频地波雷达的特点，充分发挥点迹融合与航迹融合的优点．仿真与实测数据处理结果证明本文方法的有效性，获得了跟踪性能的整体优化．

英文摘要：

Aiming at features of dual-frequency HFGWR data fusion, this paper proposes a detection area zoning hybrid fusion tracking method. In this method, the detection area is separated into two subareas, one is far subarea and another is close subarea, and there exists an acrossing belt within these two sbuareas. Measurements fusion is executed in the far subarea, single frequency tracking is executed in the close area, and the output tracks of these two subareas are then fused to form system tracks. The zoning hybrid fusion tracking method adapts well to the characteristics of HFGWR and gives full play to the advantages of measurements fu- sion and track fusion. Simulation results and measured data both demonstrate that the presented method can greatly improve the whole tracking performance.
