PLA tests midcourse missile interceptor system

PLA测试中段反导系统



China is set to become the second nation after the US to install a ground-based anti-missile shield

中国将会成为继美国之后第二个部署陆基反导的国家

By Asia Times staff February 6, 2018 4:02 PM (UTC+8)
China conducted a successful test of its ground-based midcourse defense (GMD) system this week, the Chinese Ministry of National Defense announced on Tuesday, stressing that the aim of the test was defensive in nature and not targeted at any foreign country.

本周中国国防部宣布中国成功进行了陆基中段反导测试,强调完全出于防卫目的,不针对任何其他国家。

The statement, which consisted of around 50 Chinese characters, was devoid of details on the test, but an infographic that appeared on the website of People’s Daily revealed that the system consists of a control station, sensors and interceptors.

这份声明只有50个汉字,回避了测试细节,但是人民日报网站上的一张图片揭示了这套系统包含一个控制站、传感器和拦截器。

The graphic showed that under the GMD system, X-band radars and spy satellites will first scan the skies and trigger an alarm if any incoming missiles are verified, tapping into a real-time tracking system to enumerate and calibrate with pinpoint accuracy the trajectory and velocity of any missile. Then the system will launch and guide interceptors, usually without warheads, to down the enemy missile while it is still in space and before it can re-enter the atmosphere and reach China’s airspace.

这张图片展示了在配备了中段拦截系统、x波段雷达和侦察卫星的情况下,将会先扫描天空,如果发现了来袭导弹就拉响警报,接入一套实时追踪系统高度精确地探测出任何一种来袭导弹的数量、轨迹和速度。接着,这套系统就会发射并引导通常没有弹头的拦截器,在来袭导弹还处于太空中没有进入大气层和中国领空的时候把它打下来。

It is the first time in more than three years that the People’s Liberation Army has conducted such a test, following a similar one in July 2014.

这是三年多以来PLA首次进行这种测试,上一次是在2014年七月。

Beijing’s admission of the test confirms a long-running rumor that the PLA has been researching and trialing a hit-to-kill anti-ballistic-missile defense shield comparable to the ground-based midcourse defense system that has been protecting the US mainland.

北京对于反倒测试的承认证实了长期以来PLA一直在研究测试一款可以和一直在保护美国本土的陆基中段反导系统相媲美的直接碰撞式反导防御系统的传闻。

Analysts say the US GMD and the PLA’s own system could both guarantee a higher interception rate and less collateral damage than the Terminal High Altitude Area Defense system, since THAAD only shoots down an approaching missile in its terminal phase (descent or re-entry), when it may have already pierced through the air border of  a target country.

分析称美国陆基中段反导系统和PLA的系统都可以确保有比末段高空区域防御系统(萨德)更高的拦截率和更低的附带损害,因为萨德只会在末段(再入或者下降)将来袭导弹击落,此时的导弹往往早已进入目标国家的领空了。

陆基中段反导系统是如何拦截导弹的呢?

The virtue of systems like GMD lies in a host of technological breakthroughs in ultra-long-distance sensors and new fuels and propellants to realize faster acceleration for an inceptor, among others.

相比于其他方法,陆基中段反导系统的优点在于得益于大量的超长距离感应器和新型燃料与推进剂,让更快加速度的拦截器得以实现。

Last month state broadcaster China Central Television aired a news program about an anti-missile radar station in an undisclosed location in northwestern China, highlighting gigantic X-band active phased array radars.

上个月CCTV国家广播公司播送了一档关于中国西北的某处秘密基地的反导雷达站的新闻节目,里面突出显示了X波段有源相控阵雷达。

State media have also previously revealed another such base in the northeastern province of Heilongjiang as well as P-band long-distance early-warning radars.

官媒之前也揭露了东北省分黑龙江的P波段远程预警雷达基地。
