摘要
该文对雷达和红外航迹关联决策的性能进行了分析和评估。导出了雷达与红外航迹关联时正确关联概率与关联决策门限关系的闭式解,并给出了关联决策门限与正确关联概率关系的多项式表示。在给定正确关联概率情况下,给出了错误关联概率的闭式解,并在给定错误关联概率情况下,推导出了正确关联概率的闭式解。数值计算所得精确值与近似计算所得近似值的比较表明了该方法的有效性。利用导出的这些闭式解,可以很容易地对雷达和红外航迹关联的性能进行分析和评估,并可用于对雷达和红外数据融合系统的设计。
The performance of an association algorithm for tracks generated by radar and IR sensors in terms of the probability of correct and false association is analytically evaluated. The closed form of correct association probability versus the decision threshold and the polynomial formulation of the decision threshold versus the correct association probability are derived; the closed form of false association probability for a fixed value of correct association probability is obtained; and the closed formulation of correct association probability for prescribed false association probability is also given. The derived closed formula can be easily applied to the performance evaluation of radar and IR track association and the design of radar-and-IR data fusion system.
