定向能武器是一种能产生特定方向的高能光子束或粒子束,并利用精确跟踪和瞄准系统把束流引向目标的武器系统。国外正在进行大量的研究工作,探索并论证它作为战略防御武器应用的可能性。本文主要介绍国外研究定向能武器的概况、武器结构方案、基本特性以及可能的应用领域。全文分两大部分,第一部分介绍高能激光武器;笫二部分介绍高能粒子束武器。 Orienteering weapons are weapons systems that produce high-energy photons or particle beams in a specific direction and direct the beam to a target using an accurate tracking and aiming system. A great deal of research work is going on overseas to explore and demonstrate the possibility of its application as a strategic defense weapon. This article mainly introduces the general situation of foreign countries in the research of directional energy weapons, weapons structure programs, basic characteristics and possible application fields. The full text is divided into two parts, the first part introduces high-energy laser weapons; the second part describes the high-energy particle beam weapons.
