摘　　要：以类HTV-2高超声速滑翔飞行器为研究对象,对其红外辐射特征进行了仿真分析。综合考虑了目标、背景、传输过程的方向和光谱特性,系统分析了地基平台、浮空器、天基卫星对类HTV-2高超声速飞行器的红外探测能力,得到了不同探测波段、不同探测平台的最大探测距离。研究结果表明,目标的红外辐射强度受观测方向的影响较大,最大探测距离随探测器灵敏度的增加而增大,中波波段(3.7~4.8μm、3.0~5.0μm)的探测距离比长波波段(7.7~9.5μm、8.0~12.0μm)的大。With the HTV-2-1ike hypersonic gliding aircrafts as the research objects, their infrared radiation characteristics are simulated. With the overall consideration of the direction and spectral characteristics of the target, the background and the transmission process, the infrared detection capabilities of the ground-based platform, the floating machine and the space-based satellite to the HTV-2-1ike hypersonic aircrafts are systematically analyzed, and the maximum detection distances for different detection platforms and detection wave bands are obtained. The study results show that the observation direction has a great influence on the infrared radiation intensity of targets, and the maximum detection distance increases with the decrease of the detector sensitivity. The detection distance in the medium-wave bands （3.7-4.8, 3.0-5.0 μm） is longer than that in long-wave bands （7.7-9.5 μm, 8.0-12.0 μm）.
