本文叙述了防空导弹的三种制导技术,并对广泛使用的连续波半主动自动导引系统作了详细的说明。任何防空导弹系统的目的是定位,跟踪并摧毁到达目标之前的任何敌机。为了允许用导弹致命的截击日标,必须成功地完成多项功能,包括有:初始目标的探测,导弹的发射,动力装置成功的工作,飞行时的制导与挖制,在截击点战斗部的引燃与爆炸等。本文只讨论有关制导的问题。 This paper describes three guidance techniques for air defense missiles and gives a detailed description of the widely used continuous wave semi-active automatic guidance system. The purpose of any anti-aircraft missile system is to locate, track, and destroy any enemy plane before it reaches its target. In order to allow the deadly miss-date of missiles, a number of functions must be successfully accomplished, including the detection of initial targets, the launch of missiles, the successful operation of power plants, guidance and dredging during flight, Ignition and explosion. This article only discusses the issue of guidance.
