【摘要】 针对高频雷达数据率低、系统特性和目标运动复杂的应用背景,文中提出了一种航迹滤波方法来改进对目标航迹的跟踪质量。依据目标运动所形成的航迹应该是连续光滑的原理,对动态特性完全未知的运动过程,利用回归分析建立结构简单、鲁棒性强的估计模型,通过平滑滤波获得目标运动状态的估计值,建立目标航迹。实验数据处理结果表明航迹滤波方法具有适用性广、稳健性好的特点。更多还原

【Abstract】 A new method called track filter,which improves the tracking quality of target track,is presented for the situation when the data rate is low and the system feature and the target movement is complicated as in HF radar.Based on the principle that the track formed by target motion is continuous and smooth,simple and robust estimation models can be constructed by regression analysis of the kinematics process with unknown behavior.The state estimations of the target are obtained by this smooth filter so as to establish the target track.When applied to experimental data,it is shown that the adaptability and the stability of the track filter are good.更多还原
