由磁层、电离层和高层大气组成的近地空间系统是现代战争和未来战争活动的主要空间领域,地磁场和地球电磁环境与军事通信、遥感侦察、导航定位以及高空核打击等军事行动有着密切的关系.本文根据已经公开发表于学术刊物的材料,对比分析高空核爆炸产生的人工辐射带和天然辐射带的主要特点以及灾害性空间天气事件(如亚暴和磁暴)对空间飞行器的损害,简要介绍电离层骚扰和不均匀性对通信的影响,探讨地磁场在导航定位中的可能应用.
The Earth space, including the magnetosphere, ionosphere and upper-middle atmosphere, is one of important fields concerned by modern and future wars. Military affairs, such as communication, remote sensing, navigation and direction finding, are largely dependent on the geomagnetic field and electromagnetic environment of the Earth. In this paper we intend to collects some of open information published in journals, describe the characteristics of the Earth radiation belts (both natural and artificial), discuss disasters from space weather events (magnetic storms and substorms), and search for possible application of the earth's magnetic field on navigation and direction finding.
