前言自从第二次世界大战以来,导弹在战争中已经扮演了一个日渐重要的角色。在已发表的一系列文章里,综述了惯性制导系统的发展,这种系统能把远程弹道导弹精确地导向地球座标系中的已知目标。惯性制导系统不适于对付难以预测的目标(如机动飞行的飞机)的导弹的制导。这些导弹要求能实时地探测目标的位置,并对其快速变化作出反应。为了完成这个任务,现代防空导弹采用了自动导引方式,在这个系统中探测器提供作为制导基础的目标数据。随着导弹接近目标,连续地改善目标信息的质量,因此,自动导引制导系统所提供的精度是其他形式的导弹制导系统所不能比拟的。
Foreword Missiles have played an increasingly important role in the war since the Second World War. In a series of published articles, an overview of inertial guidance systems has been developed that can accurately guide long-range ballistic missiles to known targets in the Earth’s coordinate system. Inertial guidance systems are not suitable for the guidance of missiles that are difficult to predict (such as maneuvering aircraft). These missiles require that the target’s position be detected in real time and respond to its rapid changes. In order to accomplish this task, modern air defense missiles use an automatic guidance method, in which the detector provides target data as the basis for guidance. As missiles approach the target and the quality of the target information is continuously improved, the accuracy provided by the automated guidance system is unmatched by other types of missile guidance systems.
