Dotting Processing System Based on Two Coordinate Radar

针对具有高分辨率的两坐标雷达,提出一种以滑窗检测结果为基础并以幅度最大值为中心凝聚点迹的点迹处理系统。该点迹系统将恒定虚警率(Constant False Alarm Rate,CFAR)检测原始点经过滑窗检测之后进行凝聚处理,实现对回波散点剔除、提取连续检测点、实现点迹凝聚功能,提高目标发现概率,提升检测可信度、速度分辨率、距离方位精度等。通过采集两坐标雷达外场鉴定试验实测数据,使用Matlab软件仿真,对比算法试验结果,并在服务器平台实现3 ms内对一个脉冲最大5 000点的实时处理。

For two-coordinate radar with high resolution,a tracking processing system based on sliding window detection results and centered on the maximum amplitude is proposed in this paper.The tracking system uses Constant False Alarm Rate(CFAR)to detect the original points after sliding window detection for aggregation processing,to achieve scatter elimination of echoes,extraction of continuous detection points,realization of trace aggregation,and improvement of target discovery probability.Improve detection reliability,speed resolution,distance and azimuth accuracy.By collecting the field identification test data of two-coordinate radar,using Matlab software simulation,comparing the algorithm test results,and realizing realtime processing of a pulse with a maximum of 5000 points within 3 ms on the server platform.
