导弹预警卫星探测原理及其攻防技术探讨

Analysis of the Missile Early Warning Satellites Detecting Principle and Discussion of Attack-Defence Measure

导弹预警卫星通过对弹道导弹尾焰红外辐射的探测实现主动段对弹道导弹的跟踪预警。从大气吸收的角度出发,对导弹红外预警卫星的探测原理进行了研究,通过计算说明了卫星对导弹尾焰进行红外探测的波段选择依据,并从探测距离上对该红外预警卫星的探测能力进行了建模研究。探讨了对光学探测卫星实施干扰时需要解决的问题以及卫星可能采取的防护方法。

Through detecting the infrared radiation characteristics of the missile plume, the Missile Early Warning Satellites carry out tracking and warning of the ballistic missiles. The detecting principle, including the band choosing, is studied on the basis of calculating the troposphere absorption. The detecting efficiency is analyzed using algorithm model based on detection distance. Some methods of the countermeasure against the optical Satellites and the defence measures of the Satellites are discussed.
