预警机雷达对海面目标的航迹平滑方法研究

Research on Track Smooth Processing Methods for Sea-Surface Target in AEW Radar

本文针对预警机雷达对海面大型舰船目标定位精度较差的问题,对影响定位精度的航迹抖动等因素进行了分析,提出了基于历史航迹的点坐标平滑及方向角平滑两种航迹平滑方法。最后,通过对两种平滑方法进行仿真分析,验证了方法的有效性。

The positioning accuracy of large ships is an inherent disadvantage of AEW Radar. In order to relieve this problem,the generating mechanisms of tracking jitter are researched in this paper. Based on the coordinates and the azimuth of history tracks,two smooth processing methods are proposed,the corresponding algorithm processes are given in this paper too. At last,the effectiveness of proposed methods is proved by contrast simulation experiments.
