针对现有反导预警体系对临近空间高超声速目标预警探测能力不足的问题,基于目标特性详细分析体系内各预警装备对其适用性并提出相应对策。在给出目标运动模型的基础上,通过建立红外探测模型和雷达探测模型,采取与弹道导弹比较的方式详细、定量分析目标飞行高度和横向机动能力对地基雷达的影响及红外辐射可探测性性能,并提出反临预警探测对策。分析结果表明,高超声速目标更低的飞行高度和更强的机动能力导致雷达对其搜索捕获难度更大,但其红外辐射强度大使得对其预警时间更长。仿真数据验证了分析结果的正确性,可为反临预警探测体系建设提供技术支撑。

In view of the lack of early warning ability of the existing anti-missile early warning system for near space hypersonic targets,the applicability of each early warning equipment in the system is analyzed in detail and the corresponding countermeasures are put forward based on target characteristics. Target motion model, infrared detection model and radar detection model are established first. The influence of target flying altitude and lateral maneuverability on ground-based radar and the detectability of infrared radiation are analyzed in detail and quantitatively by comparing with ballistic missiles. Then countermeasures of near space early warning detection are put forward. The analysis results show that it is quite difficult for a radar to search and capture the hypersonic target because of its lower flying altitude and stronger maneuverability, but the early warning time will be longer for its strong infrared radiation intensity. The correctness of the analysis results is verified by the simulation data, which can provide technical support for the construction of near space early warning detection system.
