随着临空高超武器陆续取得技术突破和试验成功，其对探测感知和系统防御带来的挑战也逐渐由概念设想转变为重大现实威胁。本文从临空高超目标轨道特性、运动特性、电磁散射特性对雷达探测带来的技术挑战出发，分析雷达探测临空高超目标需解决的关键技术问题，提出在临空高超目标的高速、大机动、等离子鞘套带来的目标检测、跟踪、鞘套目标识别等问题的技术解决路径。以体系化作战为核心，分析提出反临探测体系需重点解决覆盖性、时效性和协同性等关键问题，探索构建探测-跟踪-打击链闭环的探测体系需求和技术路径。

Research on Key Technologies of Radar Detection of Near Space Hypersonic Weapon

Consistent breakthroughs in near space hypersonic weapon technology are presenting existential threats to early warning detection and defense systems. In light of the challenges that the technical characteristics (orbital/motional/electromagnetic) of near space hypersonic targets pose to radar detection, this paper details the most pressing technical problems to be tackled by radar systems, and proposes corresponding solutions in detection, tracking and recognition of near space hypersonic targets that features high speed, high mobility and plasma sheath. Aiming for systemized combat operations, the paper further discusses the critical challenges of improving detection coverage, timeliness and coordination in near space target detection, and explores approaches to near space target detection system development by building a closed- loop detection-track-defeat system.
