当AESA雷达用作定向微波武器--AESA的新进展 aesa雷达

[美国《国防工业日报》2008年11月17日报道] SAIC公司收到美国科特兰德（Kirtland）空军基地空军研究实验室（AFRL）一份价值1600万美元的IDIQ研究开发合同，并发布了一份名为《电磁效应研究开发》的广泛机构公告。

研究内容将包括高能电磁波（Electro-Magnetic，EM）的破坏性能、军事装备在高能微波（HPM）环境下的生存性能、HPM武器的开发和HPM的改进——将预言性型号改进为作战型号。

军方希望SAIC公司合理运用可用的AFRL/RDH资本资产，并且增强和完善AFRL/RDH的性能，而不仅仅是从事研究。

电磁脉冲（EMP）是一种强辐射爆炸的衍生现象，常见于核武器爆炸。EMP能够烧毁其作用范围内的大多数半导体电子器件，也就是目前几乎所有的电子产品。因此核弹空爆产生的EMP就拥有了一种潜在的进攻用途。

HPM同样包含EMP，但不会如此显著。例如，人们声称现代AESA雷达能够将其阵列聚焦，在局部范围内产生HPM效应，从而使敌方雷达弱化甚至失能。

在未来十几年内AESA雷达将陆续装备俄罗斯和欧洲的战斗机，随着应用物理学相关内容研究的深入，这种物理现象将会在进攻和防御领域发挥作用。

Nov 5/08: SAIC Technology Services Co., of San Diego, CA receivedan indefinite-delivery/ indefinite-quantity contract for $16million for R&D under a Broad Agency Announcement entitled“Electro Magnetic Effects Research and Development.” This researchwill examine aspects of high power EM lethality, with missions thatinclude survivability of military equipment high power microwave(HPM) environments, the development of HPM weapons, and therefinement of HPM-predictive modeling for inclusion into engagementand campaign-level models. The military woul like SAIC to makeoptimum use of available AFRL/RDH capital assets and to augment orcomplement AFRL/RDH capabilities, rather than pursuing its researchalone. The Air Force Research Laboratory/RDKP, Det 8 Directorate ofContracting at Kirtland AFB, NM manages this contract(FA9451-06-D-0222, P00009).

EMP (Electro-Magnetic Pulse) is a side-effect of intense radiationbursts, usually from a nuclear weapon. Its effect is to fry mostsemiconductor-based electronics within its effective range, whichis to say most electronics these days. This gives EMP a potentialoffensive use via strategically placed nuclear airbursts. RepRoscoe Bartlett [R-MD] has led the charge on this issue inCongress, working to establish an EMP Commission that has reportedon the USA’s general vulnerability to such attacks, and furtherresearch continues. HPM includes EMP, but it can also be much lessdramatic.As one example, thereare claims that some modern AESA radars might be able to focustheir arrays, in order to produce a very localized HPM effect thatcould impair or even disable enemyradars.With AESA radars set to deploy inRussian and European fighters over the next decade, a betterunderstanding of the applied physics involved makes sense for bothdefensive and offensive reasons.

波音公司为美空军开发机载高能微波武器

[波音公司2009年5月15日报道] 4月27日，波音公司获得了一份价值3800万美元的合同，将为美国空军研究实验室（AFRL）的反电子高能微波先进导弹计划（Counter-electronicsHigh Power microwave Advanced MissileProject，CHAMP）开发一种非致命高能微波（HPM）机载演示器。
这项CHAMP联合性能技术演示（JointCapability TechnologyDemonstration，JCTD）计划将是第一个演示反电子HPM航空演示器的项目。
据波音公司幻影工厂（PhantomWorks）CHAMP项目经理基斯·科尔曼（KeithColeman）介绍：“这种演示器将提供一种革命性的非致命系统，能够帮助军方应对各种目标，并将附带毁伤降到最低。该系统融合了AFRL的紧凑型微波技术和波音公司的先进飞行器设计制造技术，将会催生一类新型非致命高效系统，这将改变游戏规则。”
该项目为期3年，包括地面和飞行演示，将专注于技术集成和军事应用。波音公司作为主承包商将提供机载平台和系统集成。新墨西哥州阿布奎恩（Albuquerque）市的Ktech公司作为主要分包商将提供HPM发射源。桑迪亚国家实验室（SandiaNational Laboratories）将提供脉冲电源系统。

While AESA makes fighters much more effective, it's the many otheruses of AESA that make this technology so attractive to warplanedesigners, and the Chinese. For example, the U.S. Air Force hasbeen equipping some of its fighters with electronic ray typeweapons. Not quite the “death ray” of science fiction fame, but anelectronic ray type weapon none the less. In this case, the weaponuses the high-powered microwave (HPM) effects found in AESA radartechnology. AESA is able to focus a concentrated beam of radioenergy that could scramble electronic components of a distanttarget. Sort of like the EMP (Electromagnetic Pulse) put out bynuclear weapons. The air force won’t, for obvious reasons, discussthe exact “kill range” of the of the various models of AESA radarson American warplanes (the F-35 and F-22 have them). However, it isknown that “range” in this case is an elastic thing. Depending onhow well the target electronics are hardened against EMP, moreelectrical power will be required to do damage. Moreover, theelectrical power of the various AESA radars in service varies aswell. The air force has said that the larger AESA radars it isdeveloping would be able to zap cruise missile guidance systems upto 180 kilometers away.
