美军:F22新电子战系统可永远压制中国反隐身雷达

2016-03-01 11:13:33   环球网

冷战结束之后,自居“世界警察”的美国一直陶醉于全球干涉的独大局面,但随着中国、俄罗斯等国的崛起和复苏,美国说一不二的局面正在不断瓦解, 特别是中国一系列“反介入/区域拒止”武器的出现,令美国引以为豪的海空军也不得不三思。日前美国以应对朝鲜威胁为幌子,派遣了F-22隐型战斗机等先进 进攻武器到中国周边耀武扬威,中国军事专家表示,可趁机使用反隐身雷达针对F-22进行练兵加强探测。但据最新消息,美国正在研制一种基于“人工智能 (AI)”的新型电子战系统,美军认为,如果研制成功的话,将能永远对抗中国和俄罗斯的雷达系统。

据美国“国家利益”网站2月29日报道,美国五角大楼的国防高级研究计划局(DARPA)的负责人阿拉提-普拉巴卡尔(Arati Prabhakar)表示,该项目基于一种全新的“电子战”方式。研究人员正在使用“人工智能”来实时的了解敌人雷达的动态,然后立刻编写出一种新的干扰 配置文件。整个感知、学习和适应的过程将是连续不断的。

美媒称,当前的飞机包括F-22和F-35隐型战斗机都有一个威胁库,专门储存敌方雷达信号和干扰配置文件的数据。但是如果这些飞机遇到之前从 未见过的信号时,系统将自动将其识别为未知,这意味着此时战机将易受攻击。普拉巴卡尔表示,当美军飞机出动执行任务时,它们都预先装载了一套干扰配置文 件,这些特殊的频率和波形可被发射以干扰或阻断敌人的雷达以保护自身安全。当美军飞机在冲突中遇到陌生的频率或波形时,将有可能暴露在敌人面前。

文章称,在和平时期,美军通常使用像RC-135V/W这样的信号情报飞机来收集新波形的数据。这些数据随后被送到实验室进行分析,针对其编写 新的干扰配置文件,然后更新F-22、F-35、F/A-18等飞机的数据库。最终,经过几个月甚至几年时间后,美军飞机才能够对抗这种新型的雷达信号。

普拉巴卡尔称,在信息革命之前的时间里,这种方法可能足够了,那时雷达的波形很少会改变,但是在目前,使用一个小软件就能修改波形,这让美军变 得脆弱。她表示,你可以将连接数十亿人的互联网与其相比,敌人正是使用这种技术来修改雷达的。目前美军只有EA-6B和EA-18G飞机有一定的实时分析 敌方雷达波形能力,因为只有这两种飞机搭载有电子战军官(EWO),他们能够根据经验识别和分析未知的敌方雷达波形,在一定程度上找到实时干扰的办法,但 这远远不够,因为这种方式完全依赖电子战军官的技能。

文章称,如果国防高级研究计划局(DARPA)的电子战系统有效的话,将拯救五角大楼的时间、金钱,并在未来遭遇敌人新型防空系统或战斗机雷达 时拯救机组成员的生命。普拉巴卡尔称,这意味着美军飞机在未来不必等待成年累月,在实时战斗中就能够适应和干扰敌人的新型雷达。
