航天照相侦察卫星

Aerospace Photography Reconnaissance Satellite

现代国际公约规定,一国的领空限制在80-110千米以下,在此以上像公海一样属于公空,可以自由飞行,因此容许别国飞行物,包括人造卫星,进行各种正常活动,如:探测,照相等等.航天侦察卫星就此应运而生.航天照相侦察卫星是发展最快,最成功的一类,卫星上一般安装有航天照相机或电视摄影机,对目标进行拍摄,其飞行轨道的近地点通常离地面150-280千米,所配备的摄影系统有极高的分辨率,能进行红外和多谱段拍摄,具有夜间侦察和识别伪装物的能力,集中了一些最先进的科学技术,已经取得了极佳的效果.本文对其最新的进展进行综述.

The present international convention defined that the limited to less than 80-110 km high.Over this attitude belongs to aviation to all flying objects,including artificial satellite,to do an territorial air of a country is the open air and allows free ything lawful, e.g.exploration, photography etc,thus giving a free space to aerospace photography reconnaissancc satellites which have been developing rapidly and successfully.This type of satellites flying via a locus with a nearground distance of 150-280km, are generally equipped with high resolving power aerospace camera or video camera capable of doing infiared and multi-spectra photography,uight reconnaissance and detection of fake shielding objects,have already created satisfactory results.This paper presents a review of their recent development.
