摘要:
利用低轨卫星对特定目标区域进行观测和监视在军民领域都具有很重大的意义,在系统设计 中,需要重点考虎如何对所获取的信息进行实时传输并高效处理。介绍了一种准实时目标区 域监视星座应用模式,进 行了理论分析,并以仿真说明了该模式下监视信息的传输具有较高的时效性,优于传统的星 座 应用模式。最后分析了该应用模式下涉及到的多星接入问题。

Abstract:
It is very important to observe some special area targets by low earth orbit(LEO) satellite in both military and civil applications, and how to realize realtime transmission and highefficiently processing of the obtai ned information should be especially considered in system design. A constellation application mode for quasi realtime area targets observation is i ntroduced, theory analysis is given and simulation is performed to prove its sup e riority.Finally,the multi-satellite access under the applica tion mode is discussed.
Key words:  LEO satellite  area targets observation  earth observing  quasi real time  multi-satellite acc ess
