| 中文摘要:随着临近空间高超声速技术的迅猛发展和临近空间高超声速导弹的装备使用，新的军事威胁已成为现实。由于临近空间高超声速导弹飞行弹道低且具有机动飞行的特点，需要对它进行实时探测跟踪才有可能对其飞行弹道进行预测。受地球曲率等因素的影响，地面雷达系统对临近空间高超声速导弹的探测距离有限，且组网探测对雷达数量需求庞大，因此卫星探测是一种较好的手段。对美国当前大力发展的海陆军通用型高超声速滑翔体(Common Hypersonic Glide Body, C-HGB)的红外辐射特性进行了初步分析，并结合高轨红外预警卫星的探测能力，初步分析了预警卫星对处于滑翔飞行阶段的C-HGB的可探测性。结果表明，当前的高轨红外预警卫星难以实现对处于滑翔段的C-HGB的探测，所以需要改进卫星红外探测系统或者组建低轨卫星星座。 |

| Abstract:With the rapid development of near-space hypersonic technology and the use of near-space hypersonic missiles, new military threats have become a reality. Due to the low flight trajectory of the near-space hypersonic missile and the characteristics of maneuvering flight, it is possible to predict its flight trajectory only by real-time detection and tracking. Affected by the curvature of the earth and other factors, the detection range of ground-based radar system for near-space hypersonic missile is limited, and there is a huge demand for the number of radars for networking detection, so satellite detection is a better means. The infrared radiation characteristics of the U.S. Navy and Army′s common hypersonic glide body (C-HGB) are analyzed preliminarily. Combined with the detection capabilities of the high-orbit infrared early warning satellite, the detectability of the early warning satellites to the C-HGB in the gliding flight stage is analyzed preliminarily. The results show that the current high-orbit infrared early warning satellites are difficult to detect C-HGB in the gliding phase, so it is necessary to improve the satellite infrared detection system or build a low-orbit satellite constellation. |
