Threat value of air target is that it can evaluate damage degree of attacking ground(surface) target in command and control of air defense system.

空中目标的威胁值评估是指空中目标对所攻击的地(水)面目标可能造成的毁伤程度进行评价。

A parameter estimating method for air targets by fire control system of air defense weapon is presented in allusion to the characteristics in this paper.

针对防空武器火控系统的特点,提出了一种防空武器火控系统对空中目标参数估计的方法,可以在不知道目标距离的条件下得到目标的航向角与俯仰角,实现对目标的被动式跟踪,对估计误差的统计特性进行了分析,仿真结果表明了该方法比传统的估计方法更加可行。
