基于改进“当前”统计模型的ADS-B目标跟踪方法

A Target Tracking Method of ADS-B Based on Modified Current Statistic Model

在分析ADS-B技术原理及其消息基本类型的基础上,提出了ADS-B消息接收处理流程。给出了ADS-B数据转换为便于目标跟踪的直角坐标系及极坐标系下数据格式的方法。针对"当前"统计模型及其自适应卡尔曼滤波算法对民航飞机的弱机动存在较大跟踪误差的问题,提出一种最大加速度自调整和机动频率自适应调节的新算法;理论分析和仿真结果表明,新算法较传统算法不仅保持了对机动性较强目标的良好跟踪效果,也提高了对弱机动目标的跟踪精度。

Based on analyzing the ADS--B technology principle and the basic type of ADS--B,a news receiving and processing of ADS- B is presented. For the convenience of target tracking,a method of the ADS--B data convert to the Right Angle coordinate and Polar coordinate data formate is given. To the problem of the adaptive Kaman filter which is based on current statistical model has greater tracking error for the weak motor of civil aviation aircraft, An new adaptive adjustment algorithm of maximum acceleration and maneuvering frequency is presented. The theoretical analysis and simulation results show that the new algorithm is not only maintaining a good performance for tracking the strong maneuvering target,but also better in tracking the weak maneuvering target than the conventional algorithm.
