一种浮空器雷达公路航路图积累方法

摘要

提出了一种浮空器雷达公路航路图积累方法,对雷达原始点迹进行统计和处理。该方法通过对目标原始点迹的方位宽度、距离宽度和多普勒频移进行分析,统计出公路航路上的动目标点迹。经过一定时间积累,这些点迹可以在公路航路上形成条带分布,并通过局部多项式拟合形成公路航路统计图。形成的公路图可以用于弥补缺失的地图路段或纠正电子地图误差。将公路航路统计图叠加显示在雷达显示画面上,帮助操作员迅速判断目标的类型;运用形成的公路图可以进行地面动目标点的自动剔除,使雷达显示和情报质量改善。实验结果表明该方法是切实有效的,并具有很好的实用性。%A method to accumulate the road and airline map for Aerostat radar is proposed,which can deal with the original radar plot for statistic.By analyzing the azimuth width,distance width and doppler frequency shift of the original target plot,the method can distinguish the plot of moving target on the road and airline.After a period of cumulate time,these plots can compose some strip lines on the road and airline,which can form the accumulated road and airline map by using local polynomial regression.The absent or mistaken part of map can be fulfilled or corrected by the accumulated road and airline map.By overlapping the accumulated road and airline map on the radar screen,operators can classify the target rapidly.The accumulated road and airline map can help to remove the moving target plots on the road or airline automatically,which can improve the effect of radar display and the quality of advices.Experimental results show that the proposed method is effective and well practical.
