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。
The detection of the target of the thermal layer in the cruise segment is an important target of the future space target detection system. Firstly, the THz spectral radiation characteristics of the target in the thermal layer of the cruise section are theoretically analyzed, and then the atmospheric permeability characteristics of the THz spectrum that can be detected are simulated. Theoretical calculation excludes THz spectrum radiation from the cosmic background to the space-based detection Finally, based on the current development level of THz detector, the feasibility of THz technology based on THz technology to detect thermal target in cruise section is analyzed preliminarily, and feasible approaches are also proposed.
