一、引言近十多年来反舰导弹飞速发展,它已成为现代海军的标准武备之一。导弹的发展推动着制导技术的发展,而把惯性制导应用于反舰导弹之中,无疑是其中一项十分重大的技术措施。反舰导弹有许多特点:一是弹道低,通常在15米以下,末段可掠海飞行,发现和拦截都很困难,因而突防能力强。二是使用复合制导,导弹自控段飞行采用惯性制导,自导段采用 I. INTRODUCTION The rapid development of anti-ship missiles in recent ten years has become one of the standard armed forces of the modern navy. The development of missiles has promoted the development of guidance technology. The application of inertial guidance to anti-ship missiles is undoubtedly one of the most important technical measures. Anti-ship missiles have many features: First, the trajectory is low, usually 15 meters below, the last section can be swept the sea flight, find and intercept are very difficult, and therefore penetration ability. Second, the use of composite guidance, automatic guided missile flight using inertial guidance, self-guided section
