虚假目标的判定对雷达目标跟踪具有重要影响。针对空管雷达数据中目标的运动轨迹,提出了一种基于线性回归模型的空管雷达数据虚假目标判定方法。该方法分析目标运动位置在x和y方向上的变化,建立相应的线性回归模型,进行回归诊断及残差分析,进而找到其中的强影响数据,通过分析这些数据对回归方程的影响,最终得出虚假目标的分布情况。仿真实验证明,该方法在虚假目标的判断中是有效可行的,在工程上具有较大的应用价值。
Determining false targets has important influence on radar targets tracking. In the presence of target trajectory in radar data of air traffic control(ATC) , a false targets decision method based on the line- ar statistical model is presented. Tile method analyses the change of targets' position in X and Y direc- tions, constructs the linear regression model, analyses regression diagnostics and residual analysis, then finds the influential data, through analysing the influence on regression equation ,finally obtains the distri- bution of false targets. The experiment proves that the approach is feasible and efficient to determine false targets,and also has applicalion value in engineering.
