本发明是关于导弹被动导引方法,特别适用于把导弹导至低空贴海面机动飞行的目标。大家知道,红外导引头可把导弹非常精确地导至目标。然而,这种精度只有在导弹位于目标附近时才能达到,因为,红外导引头的作用距离不超过几公里。因此,必须由电磁导引头捕获远距离上的目标。可是,很难用被动电磁导引方法把低空飞行导弹导至同样在低空机动飞行的目标,因为当前采用的导引方法给出角比例,而其导引误差随着导弹-目标距离的缩短而加大。这是由于导弹的制导系统不仅接收直接由目标发出的辐射,同时,还接收反射到海面再 The present invention relates to a method of passive guidance of missiles, and is particularly suitable for the purpose of guiding missiles to the maneuvering surface at low altitude. As we all know, infrared seekers can guide missiles very accurately to the target. However, this accuracy can only be achieved if the missile is located close to the target because the infrared seeker does not move for more than a few kilometers. Therefore, targets on long distances must be captured by the electromagnetic seeker. However, it is very difficult to use passive electromagnetic guidance to guide low-level missiles to the same flight maneuvering at low altitudes because of the current guidance method which gives the angular ratio and the guidance error decreases as the missile-target distance decreases Increase. This is because the missile’s guidance system not only receives the radiation emitted directly by the target but also receives reflections to the sea and then
