【摘要】：单频率高频地波雷达海上目标探测会受到一阶海杂波和高频谐振区目标回波强度起伏的影响,引起目标漏检。利用实测船只探测实验数据,分析了双频地波雷达目标探测的特点,并重点分析了海杂波对目标探测的影响,指出双频雷达可以克服单一频率目标探测中漏检的缺陷,提高船只目标的检测率。通过分析双频地波雷达检测结果的不同分类及处理方式,给出了双频地波雷达目标点迹融合处理方法,讨论和分析了目标点迹关联中距离门、速度门和方位门等参数的选取原则及影响因素。最后利用实测同步的自动识别系统数据,评价了目标点迹融合的探测精度。
[Abstract]:Single frequency HF ground wave radar detection of sea targets will be affected by the intensity fluctuation of the first order sea clutter and the high frequency resonance region, which will cause the target to miss detection. The characteristics of dual-frequency ground wave radar target detection are analyzed, and the influence of sea clutter on target detection is analyzed. It is pointed out that dual-frequency radar can overcome the defect of missing detection in single frequency target detection. By analyzing the different classification and processing methods of the detection results of dual-frequency ground wave radar, the fusion processing method of target track of dual-frequency ground wave radar is presented, and the middle distance gate of target point trace correlation is discussed and analyzed. The selection principle of velocity gate and azimuth gate and its influencing factors are discussed. Finally, the detection accuracy of target track fusion is evaluated by using the measured data of automatic recognition system.
