EKV红外导引头探测距离估算

Estimation of Detecting Range for IR Sensor on EKV

外大气层杀伤拦截器（exoatompropheric kill vehicle,EKV）是地基拦截导弹（ground based interceptor,GBI）上的拦截设备,是地基中段防御系统中的重要组成部分,是以直接碰撞杀伤的方式对弹道导弹弹头进行中段拦截的飞行设备.对EKV上红外导引头的各项探测性能参数进行了分析,分别推导了空间冷背景下和大气背景下红外导引头对点目标的作用距离方程,并对相应方程中的各项参数和影响因素进行了分析,估算了在空间冷背景下和大气背景下EKV的探测距离数据.

The Exoatmospheric Kill Vehicle （EKV） is the intercept component of the Ground Based Interceptor （GBI） and the weapon element of the Ground-based Midcourse Defense System, which is a vehicle to engage high-speed ballistic missile warheads in the midcourse phase of flight and to destroy them using only the force of impact, or hit-to-kill. The parameters about detection performance of IR sensor on EKV are analyzed, and the equation of the range of action for point target detection is derivated either in the space dark background or in the atmosphere background. After dis cussing the parameters that affect the result, the EKV range of action is estimated.
