摘要
在不引入续航发动机推力的前提下,考虑速度约束和过载要求,提出了一种适合图像制导导弹搜索和攻击的弹道方案。导弹先以较低高度飞行,便于导引头搜索,发现并锁定目标之后二次爬升到较高的高度,再转入满足落角要求的攻击。阐述了飞行高度对导引头搜索视场和攻击落角的矛盾影响,分析了二次爬升过程中速度减小量和爬升高度的关系。计算结果表明此方案可行,解决了搜索视场和攻击落角矛盾。
On the premise of not using sustainer motor, considering velocity constraint and overload requirement, a trajectory project for the image guided missile is proposed. Missile flies at a lower height which is good for the image seeker searching. After the seeker captures and tracks the target, missile climbs to a higher height in order to attack the target at a large angle. The contradietive effects of flying height on searching visual field and attacking angle were expounded in detail The relationship between velocity decreasing and climbing height during climbing project is discussed. Finally, an example result indicates the feasibility of the proposed project. It solves the contradiction of searching visual field and attacking angle.
