综合考虑电视制导攻击型无人机在搜索地面目标过程中导引头的地面视场、搜索盲区和目标图像移动等关键因素对目标截获的影响,建立了无人机飞行高度、飞行速度与导引头目标搜索之间的数学模型,推导出了一种电视导引头搜索规律,可以从3个方面提高目标截获概率:①可以补偿因无人机向前飞行而引起的目标图像纵向移动,使显示在地面站监视器中的目标画面在导引头搜索过程中只作水平方向的移动,利于"人在回路"使用方式下地面站射手对图像的分析、判断;②通过导引头光轴俯仰搜索角度和无人机飞行高度匹配设计,可以保证地面视场最大;③通过导引头搜索周期和无人机飞行速度协调设计,可以实现对目标区无漏扫. 该搜索规律通过在某电视制导攻击型无人机中应用进行了可行性验证.

The searching problem of television ( TV) image seeker for attack UAV is addressed. The desired goal in the problem is to minimize the searching blind field, maximize the field of view projecting on the ground and to e?liminate the image up?down motion on the monitor′s screen, simultaneously. A searching law was deduced based on the mathematical model of the relationship among UAV′s flying velocity, flying height and the seeker′s searching motion. The law can improve the target catching probability by a matching design between TV seeker searching and UAV flying and its feasibility was validated by an application on a TV guided attack UAV.
