摘　　要：等离子鞘套引起的“黒障”问题是各国航航空航天研究的热点和难点。滑翔飞行器在临近空间高速飞行,产生“等离子鞘套”效应,严重影响地面监测装备对目标的外弹道测量、控制。本文研究了等离子鞘套产生的原因,分析对雷达检测产生的影响,设计采用常规跟踪波形驻留+PD脉冲串驻留交替波形的跟踪策略,并通过典型场景应用与验证。The“black barrier”problem caused by plasma sheath is a hot and difficult topic in the aerospace research of various countries.Gliding aircraft flying at high speeds in near space generate a“plasma sheath”effect,which seriously affects the external ballistic measurement and control of targets by ground monitoring equipment.In this article,the causes of plasma sheath generation was studied,its impact on radar detection was analyzed,and a tracking strategy was designed using conventional tracking waveform persistence+PD pulse train persistence alternating waveform,and verified it through typical scenario applications.
