为提高对加固掩体、地下指挥控制中心等硬目标的毁伤效果,新型空地导弹需要使用较大的落角攻击目标。文中首先对两种可实现大落角攻击的制导方式——————过重补比例导引和Zarchan弹道成型制导律进行了仿真分析,并提出了“Zarchan弹道+比例导引”组合制导方式,仿真分析表明,该组合制导方式可实现接近90°的末端落角,比较适合于防区外发射空地导弹和高空投放的制导炸弹。

To achieve better lethality for attacking hard targets such as strongly reinforced bunkers, and underground command and control centers, many state-of-the-art air-to-ground missiles need higher impact angles. Over-compensated proportional navigation and trajectory shaping guidance proposed by Zarchan were analyzed and simulated. A new guidance law that combines the method of Zarchan's trajectory shaping guidance and proportional navigation was proposed and studied. The simulations indicate that it can get nearly 90°impact angles, and it is very suitable for standoff air-to-ground missile and guided bombs released from high altitude.
