本专利的背景本专利与主动制导之空对空导弹有关,尤其是与制导及控制设备有关。飞机发射主动制导空对空导弹,常用一相对于被追踪的目标的大的初始速度向量角度差进行。由于导弹的固有方向来自载机机体纵轴,其初始角度差必然出现,这时,载机的机体轴不一定总是指着发射时所指的目标的方向。在大多数情况下,空对空导弹发射 Background of the Invention This patent relates to active guided air-to-air missiles, and in particular to guidance and control equipment. Aircraft launch active-guided air-to-air missiles, often using a large initial velocity vector angle difference relative to the target being tracked. Since the inherent direction of the missile comes from the longitudinal axis of the carrier body, the initial angular difference is bound to occur. In this case, the body axis of the carrier does not always point in the direction of the target at launch. In most cases, air-to-air missile launches
