一、引言六十年代以来,现代防空导弹在射程、射高、射击效率以及机动性能等方面有了很大的提高,为逃避防空火力的打击和提高攻击能力,各国的空袭兵器向低空发展,并广泛地采用低空突防的战术。因此,射击低空目标成为值得普遍重视的问题。在射击低空目标时,由于目标高度低、高低角小,地空导弹发射阵地的选择有一些新的 I. INTRODUCTION Since the 1960s, modern anti-aircraft missiles have greatly improved their range, shooting height, shooting efficiency and maneuverability. In order to evade anti-aircraft firepower and increase their attack capability, the air-to-air weapons of various countries have developed at a low altitude. And widely used tactical low penetration. Therefore, the target of shooting low altitude has become a problem that deserves universal attention. When shooting low-altitude targets, due to the target height is low, high and low angle, the choice of surface-to-air missile launch positions have some new
