摘要
如何设计和实现适合空管系统使用的自适应滤波器成为了实现航迹滤波和目标跟踪的关键。首先对飞行器的三维空间运动轨迹建模"拉格朗日"(Lagrange)三阶级数展开,基于此设计了一种兼顾实时性和预测滤波效果的数据处理算法,通过对该滤波器模型稳定性、初始状态、收敛性、滤波参数等的深入分析,提出了一种基于"查表"策略的"残差-新息"估计方法,在保证收敛性的同时兼顾了收敛速度,一系列建模仿真和飞行试验均表明了所论述关键技术的有效性。
How to design and implement the adaptive filter for air traffic control system has become the key to realize trace filtering and target tracking. This paper firstly models the 3D spatial trajectory of the aircraft by three order Lagrange expansion, and designs data processing algorithm considering both real-time and predictive filtering effect based on this model, and proposes one ＇relics-innovation＇ estimation method based on ＇Looking Up Table＇ strategy by thorough analysis of the stability, original state, convergence and filter parameters of the filter model, which ensures both reliability and speed of system convergence. The effectiveness of the key technology in this paper is demonstrated by a series of simulations and flight tests.
