美國防禦高超聲速武器新漏洞曝光:雷達不夠強大,太空平台也發現不了

【环球网报道 记者 张海潮】由于担心美国军方探测在低空飞行的高超声速武器能力,美国议员希望五角大楼提交关于如何努力弥补这一差距的进度报告,特别是通过商用解决方案。据悉,美国部署的天基传感器无法探测低空高超声速武器。目前唯一方法是使用陆基高功率雷达,但现有雷达不够强大,不具备探测需要的分辨能力。

据《防务新闻》9月14日报道,美国众议院军事委员会的2022财年国防授权法案若通过,美国防部将按要求在短短几个月内,今年11月底提交一份报告,说明其使用雷达探测低空高超声速武器能力的努力状况。

报道称,该法案修正案显示,众议院军事委员会“担心当前的(美国)雷达系统无法探测、跟踪、拦截和击败新兴的高超声速武器威胁”。

议员们希望美国空军和导弹防御局检查当前的导弹防御工作,并决定是否“考虑商业上可用的创新和具有成本效益的解决方案”。他们还想知道,对于可以探测高超声速武器、填补“空白差距”的雷达进行了哪些投资,这些投资与商业上可用投资的成本比较,以及五角大楼在2023财年开始的未来预算中需要什么来填补空白。

报道提到,一位匿名行业专家表示,探测低空飞行,即大约在500英尺(约152米)高度贴地飞行的高超声速导弹,是个特别难解决的问题。

天基的太空传感器无法解决这个难题,因为位于太空的雷达或红外摄像机只能发现在高空或中空飞行的高超声速导弹,对于低空飞行的导弹,看起来就像是非常暗淡的点,很难与其他地面的杂波区分开来。太空平台也无法达到探测所需要的功率。因此,探测低空高超声速武器的唯一方法,是在地面上使用高功率雷达。

据专家介绍,(美国)现在运行的雷达不够强大,也不具备发现高超声速导弹所需的高分辨率。
