美国展示“爱国者”系统新体制雷达 现在不卖台湾

2016-03-17 08:46:55   观察者网

美国《防务新闻》网站3月15日报道,美国雷神公司在最近的美国陆军协会年会(AUSA2015)上展示了为“爱国者”系统设计的下一代雷达。这种新型雷达采用了有源相控阵体制和氮化镓芯片,在各方面性能上比旧的采用无源相控阵体制AN/MPQ-53/65雷达有很大提高,尤其是多目标交战性能。雷神公司表示将向所有装备爱国者的军队推荐这种新型雷达,不过在其公布的已经确定将更换新型雷达和潜在客户名单中,不包括台湾。

美国《防务新闻》网站报道,在阿拉斯加举行的美国陆军年会上,雷神公司展示了其第一台全尺寸“下一代爱国者雷达”原型机。

雷神公司称这种新雷达为“氮化镓有源相控阵雷达”,这种雷达的主要设计特点是让爱国者导弹系统获得360度监控范围。

雷神称,新型雷达具有两大特点。

氮化镓芯片:该雷达的芯片采用了氮化镓材料。这种新型半导体材料可以大大提高能源效率并提高雷达的发射功率。

有源相控阵:爱国者导弹此前装备的AN/MPQ-53和AN/MPQ-65(分别配备给爱国者PAC2和PAC3)雷达采用的还是无源相控阵集输,新型有源相控阵雷达改变了工作方式,提高了性能。

“这一技术到现在已经准备就绪,”雷神公司副总裁和防空反导升级项目经理拉尔夫·安卡达说“它已经准备好上战场。”

事实上,该系统也确实将在今年下半年开始进行实战测试,安卡达在揭幕仪式上向人们说。

在接受采访的时候,安卡达表示,雷神公司在过去16年中为氮化镓项目投资超过2亿美元,此外还有美国政府投资(据称约1亿美元)。

爱国者系统1982年装备美国陆军,此后雷神公司一直持续为美国和其他13个盟友国家提供升级服务。这一系统估计至少将服役到2040年。

不过雷神公司并不能因此而松懈,洛克希德·马丁公司已经开发了一种与之竞争的新型防空系统,称之为中程增强防空系统(MEADS),这种导弹与雷神公司的爱国者系统构成了直接竞争关系。

美国陆军2017财年将开始为一个新的竞争项目胜者提供资金,新项目称为IAMD雷达。这一项目的具体要求或者竞争方式尚未公开。但安卡达表示,他们的新型雷达将很容易利用美国现有的雷达系统基础进行升级。

旧式AN/MPQ-53/65雷达

此外,这次展示的新型雷达还有两个主要特点:

可以提供360度视野范围的后方天线阵列

为未来陆军升级防空反导系统预留了足够的空间。

另据美国《军事科技》杂志网站报道,这种雷达采用的氮化镓芯片带来了巨大的优势,氮化镓芯片的能量密度是传统芯片的5-10倍,因此如果使用相同尺寸的芯片,功率就会相应的大幅度增加。雷神公司称,爱国者新型雷达的搜索空域增加了5倍(观察者网注:如果扫描角度不变,探测距离增加约1.7倍)

此外,所有“爱国者”导弹用户都可能会对新型雷达有兴趣,因为如果使用新型雷达替换老式雷达,只需要做少量软件变更。

2015年,雷神公司已经获得了美国政府关于出口新型雷达的许可,目前波兰、希腊、日本和西班牙已经在考虑更新他们的“爱国者”导弹系统,瑞典、捷克和芬兰可能也会选用新型雷达,而罗马尼亚和土耳其则可能也会加入“爱国者家族”。

不过,目前台湾似乎尚不在更新爱国者雷达的行列之中,去年台湾购买的爱国者PAC3导弹系统刚刚到货,这一系统继续使用AN/MPQ-65雷达。
