美反导专家:美在韩部署萨德也无法拦截朝鲜导弹

朝鲜最近火箭发射的爆炸技术表明拦截弹无法识别潜在弹头

一位导弹防御系统的专家称,朝鲜2月7日发射的远程火箭上的自毁爆炸技术,将使美韩即将决定部署在朝鲜半岛的末段高层防御系统(THAAD萨德)失去作用。

朝鲜火箭发射和美韩开始正式讨论THAAD系统部署之后,麻省理工学院的退休教授西奥多·波斯托尔(Theodore Postol)接受韩民族日报(Hankyoreh)的采访,通过一系列电子邮件和电话采访进行了解释。

波斯托尔教授曾就读于MIT大学并获得博士学位,他曾是美国海上作战部长的资深顾问。他还曾为美国国防部、阿贡国家实验室和美国国会工作,对导弹防御系统进行了30多年的学术研究。

波斯托尔教授特别留意到朝鲜火箭发射中,火箭第一级爆炸解体为数百块碎片。事实上,2月9日韩国国防部指出韩国的宙斯盾雷达发现火箭第一级爆炸为270多块碎片。韩国国防部称,据信这次爆炸是箭上的自毁机构引发的,目的是阻止韩国搜集火箭残骸。

波斯托尔教授称,朝鲜的劳动导弹使用同样的自毁技术的话,当THAAD系统发射拦截弹时,朝鲜可以引爆导弹弹体,阻止THAAD系统的雷达识别出真实的弹头。

波斯托尔教授指出,“火箭动力飞行段结束时,它已经位于很高的高度,没有空气阻力把较轻的目标和较重的目标分开”, “因此,如果一枚导弹在动力飞行结束后碎为很多片,所有的碎片都会在弹头周围以同样的弹道飞行”,“将导弹炸为大量碎片制造出了大量假目标,而一个远处的红外制导拦截弹无法看到细节”。简而言之,由于存在大量几乎相同的目标,拦截弹将会失去拦截能力。

波斯托尔教授解释说,“拦截弹看到的所有光点都无法确认(为弹头),其中任何一个都可能是弹头”。他特别强调说“目标在拉长和翻滚...旋转中相对拦截弹方向投影面积大小变化,它们的亮度随之改变。然而这毫无价值,因为任何目标包括弹头也会翻滚“。波斯托尔教授接着说,“这项技术可以应用在朝鲜瞄准韩国的携带核弹头的劳动导弹上”。

波斯托尔教授还严厉批评了韩国和美国公开声称的THAAD系统不对中国构成威胁的说法。面对声称部署在朝鲜半岛上的THAAD雷达无法工作在前置部署模式下的说法,他回应:“说THAAD火控雷达无法使用前置模式,相当于说一辆坦克可以跑到100公里外的地点后返回出发地,但是无法单程跑200公里到一个更远的地方”。

他还补充说,“在现有技术水平下,韩国政府和人民选择部署THAAD系统是自己的权利,但是他们不应该将部署行动建立在中国无法正确认识到THAAD系统雷达对其核威慑力量威胁的错误观念上”。

最后,波斯托尔教授指出他拥有与驻韩美军第八集团军司令托马斯·汪达尔和驻韩美军司令柯蒂斯·斯卡帕洛蒂“同等水平的办公室经验”。

他说,“我作为一个美国公民,看到两位美国高级将领通过火上浇油的渲染对(朝鲜)远程火箭和核武器研制杞人忧天般的恐惧,不恰当的试图影响韩国的国内政治决策,感到非常不安”。
