摘　　要：巡航段热层目标的探测是未来空间目标探测系统的重要目标。首先对巡航段热层目标自身的THz谱段辐射特性进行了理论分析,然后对可探测THz谱段的大气透过特性进行了仿真,通过理论计算排除了宇宙背景THz谱段辐射对天基探测的影响;最后结合目前THz探测器的发展水平,重点对天基THz技术探测巡航段热层目标的工程可行性进行了初步分析,并提出了可行的技术实现途径。Detection of thermosphere target on the cruise phase is important for the future Space-based reconnaissance and surveillance. THz radiation of thermosphere target on the cruise phase was analyzed theoretically at first. Next, the transmission characteristic of the chosen THz band in atmosphere was analyzed by simulationwith the conclusion that the influence of the cosmic background radiation is insignificant. Combined with the current development of THz detectors, the feasibility of detecting thermosphere target on the cruise phase using space-based passive THz detector is discussed in detail. Finally, a possible solution is proposed.
