The original title: China successfully conducted mid-base anti-missile interception technology test
On February 5, 2018, China conducted a pilot technology test on the mid-base of anti-missile intercept in land-based territory, which achieved the expected goal. This experiment is defensive and does not target any country. The company is located in:
Previously China conducted three tests
On January 11, 2010, China conducted a pilot land-based mid-section anti-missile interception test in China. On January 7, 2010, the United States announced that it will sell the "Patriot" missile system to Taiwan. Some experts speculate that the Chinese missile test is very It may be related to arms sales by the United States to Taiwan. However, the Chinese Foreign Ministry said the trial is defensive and not aimed at any country.
On January 27, 2013, China again conducted a land-based mid-section anti-missile interception technology test in China, which achieved the desired goal. This experiment is defensive and does not target any country.
On July 23, 2014, China conducted a ground-based ABM technology test in China, which achieved the desired goal.

REVIEW: On the evening of the 27th, reporters learned from the Information Department of the Ministry of National Defense that on January 27, 2013, China once again conducted a pilot technology test of anti-missile interception in the middle of the land-based territory. The experiment achieved the expected goal. This experiment is defensive and does not target any country. So the land-based anti-missile intercept is a concept of what? Its technical difficulties where? What are the elements? Ben Wang organize the following information for users reference.
Ballistic missile flight in three phases
The first phase is the process by which a missile is launched from launch pad into the atmosphere and the missile is flying out of the atmosphere. This phase is a flight in the atmosphere and is commonly referred to as a missile ascent.
The second phase is that the missiles that fly out of the atmosphere and fly outside the target area in the atmosphere are commonly referred to as the mid-flight.
The third stage is the process of reaching the target area near the target area, returning to the atmosphere and hitting the target. The process is generally referred to as re-entry into the atmosphere or reentry section.
Interception technology for three different flight phases
In fact, the current ABM technology is mainly aimed at intercepting these three different flight phases:
Interception technology for the ascent section is the ascent section interception technology. From the stage of the missile flight, the earlier the interception effect will be, the development trend of the international anti-missile technology is to intercept it as early as possible. If it can intercept in the ascent section Is the best, but the difficulty is the greatest. At present, the typical ascent section intercepting technology is the ABL airborne ABM system that was tested by the United States on a Boeing 747 aircraft.
The second is in the middle of the ballistic missile flight, that is, in the atmosphere to implement interception technology, which is what we call the mid-land anti-missile interception technology. The blocking effect at this stage is also better.
Finally, it is aimed at the last stage of the missile flight, that is, re-entry into the interception of the technology, commonly known as the last paragraph interception technology. The last stage of interception is actually implemented in the atmosphere of interception. At present, what we see most should be the last stage of interception techniques such as the United States, "Patriot 3", Russia's S-300 and S-400. These missiles all have the capability of intercepting the last stage of the missile in the atmosphere, and they all fall into the category of the last stage of anti-missile technology.

The interception of the middle and the interception of intercept shells, height, range, different goals
As for the interception, the interception altitude is tens of kilometers, usually 20-30 kilometers, and the radius of the interception area is also tens of kilometers. Ballistic missiles in the middle of the atmospheric flight altitude is very high. In general, the interception height and extent of the interceptor hurdle are much greater than those of the interception hurdle and are usually over a few hundred kilometers. Therefore, the interceptor used in the interception of the interception and the last paragraph is completely different.
There is a big difference between the middle-level interception technology and the last-level interception technology. The targets intercepted are quite different. The last stage of interception for a variety of targets, can be for long-range ballistic missiles, but more for short-range ballistic missiles, such as "Scud." The middle interception missile is aimed at the long-range or even intercontinental ballistic missiles.
Interception of interception in the middle of the missile is a "small missile"
The middle interceptor missile is actually composed of a large booster rocket and an interceptor warhead. We all understand that the rocket is the rocket launch, sending the warhead to the atmosphere.
So what is the warhead? In fact, the mid-range warhead is equivalent to a small "missile," but the warhead looks different from a typical missile in that it is in outer space and has no air resistance, so the appearance is not like in the atmosphere Flying missiles so "stress", do not need to do aerodynamic considerations.
Although the appearance is different, but "sparrow is small, all-inclusive." This "small missile" has motivation, tracking, target recognition and other systems, along with its own anti-personnel component. The power system should promote the warhead and eventually target the target. The guidance system captures the physical characteristics of the target missile, especially the infrared characteristics, tracks it, identifies and guides the powered warhead and the target to collide and destroy it.

The technical difficulty of intercepting a weapon system in the middle is to intercept warheads
The middle-section intercepting weapon system consists of booster rocket and warhead, and the technical difficulty is intercepting the warhead. Because they can not be large and heavy, interceptor warheads have a miniaturized structure. At the same time, warhead flight precision demanding, there must be very sensitive target capture guidance system. In addition, the command system computer computing power should be strong, fast.
Of course, booster rockets also need to have certain requirements, preferably quick-fire rockets, so as to send the ABM interceptor warhead into the atmosphere in the shortest possible time. In addition, the booster rocket control accuracy requirements are quite high, if the error exceeds the range of warhead guidance system can capture, can not achieve interception effect.
Anti-missile interception in the middle is an actual combat system
Anti-missile interception system in the middle, not only missiles, but also a strong early warning and monitoring network, is an actual combat system.
Ballistic missiles from launch to enter the middle of the flight time is very short, if you want to intercept in the middle, it is necessary as early as possible to find each other's launch of the ballistic missiles at the same time to be tracked above it, calculate the flight trajectory, so as to calculate the most Good interception point, followed by the middle interception missile launched to the interception position, release interceptor warhead. In this way to complete a complete interception process.
Therefore, to form a perfect middle-range anti-missile interception system is a very complex project and requires a powerful missile warning and monitoring system. At the heart of this early warning and monitoring system is the missile early warning satellite, as well as some remote monitoring and control radar, Have efficient and quick command system.
After the information obtained by the information system enters the command system, it should be processed rapidly by the computer to design intercepting elements for the intercepting section and design intercepting bombs. The intercepting bombs enter the space with enough accuracy to release the warhead and warhead to capture the target bombs The projectile propulsion system propels the interceptor warhead, which, guided by the guidance system, reaches precisely near the interception target and destroys the ballistic missile to be intercepted.

深度解读:陆基中段反导拦截技术

导读:记者27日晚从国防部新闻事务局获悉,2013年1月27日,中国在境内再次进行了陆基中段反导拦截技术试验,试验达到了预期目的。这一试验是防御性的,不针对任何国家。那么陆基中段反导拦截是一个什么概念?它的技术难点在哪?又由哪些构成要素?本网整理以下资料,供网友参考。
弹道导弹的飞行分三个阶段
第一个阶段是导弹从发射架发射到导弹飞出大气层的过程,这个阶段是在大气层内的飞行,一般称为导弹的上升段。
第二个阶段就是导弹飞出大气层外,在大气层外向目标区域飞行的过称,一般称为飞行中段。
第三个阶段就是导弹到达目标区域上空附近,重返大气层,命中目标的过程,一般称为重返大气层阶段或再入段。
针对三个不同飞行阶段的拦截技术
实际上,目前的反导技术主要是针对这三个不同的飞行阶段进行拦截的技术:
针对上升段的拦截技术就是上升段拦截技术,从导弹飞行的阶段来看,拦截的越早效果会越好,因此国际反导技术的发展趋势是尽可能地提前拦截,如果能在上升段拦截是最好的,但难度也是最大的。目前典型的上升段拦截技术有美国试验的装在波音747飞机上的ABL机载反导武器系统。
第二种是在弹道导弹的飞行中段,也就是在大气层外实施拦截的技术,这就是我们所说的陆基中段反导拦截技术。这个阶段的拦截效果也是比较好的。
最后,就是针对导弹飞行的末段,也就是再入段进行拦截的技术,一般称为末段拦截技术。末段拦截实际上是在大气层内实施拦截的。目前,我们看到最多的应该是末段拦截技术的武器,比如美国的"爱国者3"、俄罗斯的S-300和S-400等。这些导弹都具备在大气层内针对导弹的末段进行拦截的能力,它们都属于末段反导技术的范畴。

中段拦截与末段拦截的拦截弹、高度、范围、目标不同
就末段拦截来说,它的拦截高度是几十公里,一般为20-30公里,拦截范围的半径也是几十公里。而弹道导弹在大气层外的中段飞行的飞行高度是很高的。一般而言,中段拦截弹的拦截高度和范围比末段拦截弹要大得多,通常都在几百公里以上。所以中段拦截所使用的拦截弹与末段拦截完全不同。
中段拦截技术和末段拦截技术还有一个很大的区别就是所拦截的目标有很大差别。末段拦截针对多种目标,可以针对中远程弹道导弹,但更多的是针对近程弹道导弹,比如"飞毛腿"。而中段拦截弹则是针对中远程乃至洲际弹道导弹。
中段拦截的拦截弹是一个"小导弹"
中段拦截导弹实际上是由一个大型的助推火箭和拦截弹头这两部分组成。 助推火箭我们都理解,就相当于运载火箭,把弹头送到大气层。
那么,弹头是什么样的呢?实际上,中段拦截的弹头相当于一个小的"导弹",不过这个弹头在外观上看起来与一般的导弹有所不同,因为是在外太空飞行,没有空气阻力,所以外型不像在大气层内飞行的导弹那么"讲究",不需要做空气动力学等方面的考虑。
虽然外型有所不同,但"麻雀虽小,五脏俱全"。这个"小导弹"有动力、跟踪、目标识别等系统,同时有自己的杀伤部分。动力系统要推动弹头,最终瞄准目标弹;制导系统捕捉目标导弹的物理特征,特别是红外特征,对它进行跟踪、识别,引导带有动力的弹头和目标弹相撞,将其摧毁。

中段拦截武器系统的技术难点在拦截弹头
中段拦截的武器系统就是由助推火箭和弹头组成的,而技术难点就在拦截弹头。由于不能做得很大、很重,因此,拦截弹头拥有小型化的结构。同时,弹头的飞行精度要求很高,要有很灵敏的目标捕获的制导系统。另外,指挥系统计算机的计算能力也要很强,速度要很快。
当然,助推火箭也要有一定的要求,最好是速燃火箭,这样才能在尽可能短的时间里把反导拦截弹头送入到大气层。另外,助推火箭的控制精度要求也相当高,如果误差超过弹头制导系统所能捕获的范围,也不能达成拦截效果。
中段反导拦截是一个实战系统
中段反导拦截系统,不仅有导弹,还要有强大的预警和监测网络,是一个实战系统。
弹道导弹从发射到进入中段飞行的时间很短,如果想要在中段实施拦截,就要尽可能提前发现对方发射的弹道导弹,同时要在其上方进行跟踪、计算飞行弹道,这样才能计算出最佳拦截点,紧接着将中段拦截弹发射到拦截点的位置,释放拦截弹头。这样才算完成一个完整的拦截过程。
因此,构成一个完善的中段反导拦截系统是很复杂的工程,要有强大的导弹预警监测系统,而构成这个预警监测系统的核心就是导弹预警卫星,还要辅助于一些远程测控雷达,同时还要有高效、快捷指挥系统。
信息系统获取的信息进入到指挥系统后,要通过计算机快速处理,为拦截段设计拦截诸元、设计拦截弹;拦截弹以足够的精度进入到空间位置,释放弹头,弹头工作,捕捉到目标弹;弹头的推进系统推进拦截弹头,在制导系统的制导下,精确地到达拦截目标附近,摧毁所要拦截的弹道导弹。(来源:新华网)
