摘　　要：在复杂海杂波中检测出海面目标并实现稳定跟踪一直是舰载雷达进行海面目标处理时面临的难题。文中在分析雷达常规杂波抑制方法的基础上,分别从雷达调度控制、点航迹处理等方面,给出了圈间变频、基于宽度的幅度加权点迹凝聚、海面目标的机动加速度突变跟踪模型等数据处理方法,针对性地降低海杂波影响,提高海面目标的点迹质量及跟踪性能。通过对某导航雷达实录数据进行处理,文中所提方法能有效地抑制海杂波,显著提高海面目标跟踪的稳定性。It is a difficult problem for ship-borne radar to detect and track sea targets in complex sea clutter.Based on the analysis of the conventional clutter suppression methods of radar,this paper presents data processing methods such as inter cycle frequency conversion,width based amplitude weighted spot condensation,and sea target's Acceleration Gust model from the aspects of radar scheduling control and point track processing,aiming at reducing the impact of sea clutter,improving the spot quality and tracking performance of sea target.Experimental results show that the proposed method can effectively suppress sea clutter and significantly improve the stability of sea target tracking.
