连续波半主动雷达制导空空导弹截获跟踪距离计算

Consideration on calculating capture and tracking range of CW guided air-to-air missile

分析了连续波半主动雷达制导导弹导引头工作电磁环境和对武器系统攻击区的影响。建立了热噪声和杂波干扰环境下导引头截获距离方程 ,分析推导了直波泄漏干扰、地杂波干扰的计算公式 。

The magnetic environment in which the CW semi active radar guided missile's homer works is analyzed and its influence on the attacking envelope of the weapon system is given. The homer capture range equation under the interference of hot noise and clutter is built, and the formula for calculating the interference of direct wave leakage and ground clutter is deduced, on which basis the formula of permissible attacking envelope is given.
