中国超级雷达数百公里外破解F22隐身秘密 美开始仿制
中国超级雷达数百公里外破解F22隐身秘密 美开始仿制
208
日前，网络曝光了两条消息，非常有意思。首先是中电科首席科学家吴剑旗，公开做了国内关于反隐身先进米波雷达的报告，称2013年首次探测到了450公里外的F22，并且绘制了它的飞行轨迹，当时其他雷达没有发现目标。
吴剑旗总师公开讲解中国米波反隐身雷达
其次，12月13日，美国洛克希德·马丁公司公开展示一款最新研制的TPY-X陆基远程多任务雷达系统原型，无论是雷达天线外形，还是技术体制、功能用途描述，都和2014年11月的第十届珠海航展上，中国军工展示的JY-26型米波反隐身相控阵雷达系统同出一辙！今天我们就来聊聊这两个事。
中国JY-26型米波反隐身相控阵雷达
美国TPY-X陆基远程多任务雷达系统原型，跟中国的是不是很像？
很早以前，在军迷圈就有传言称我国探测到美军F22隐身战机，甚至有击落F22或者F22叛逃的消息，此后几乎每年都有一个新版本的传说。如今看来确实是无风不起浪。（当然，击落F22或者F22叛逃，其实就是我国做了一个美军五代机的特征识别模型，正好被卫星拍到而已。）根据吴剑旗总师的说法，中国是第一个成功研发并部署米波反隐身雷达的国家。米波雷达有三个重大缺陷：低仰角盲区大，该波段在低于一定角度就会发生镜面反射，不能准确测高，而且空域覆盖不连续。
052C驱逐舰舰体中部就是很典型的米波反隐身雷达
而实际上，早在中国之前，美国和俄罗斯就已经开始预研过米波雷达，但是因为无法克服前面所说的三大缺陷，认为不可能就放弃了。更重要的是，美国一直认为，在可预见的时间内，其他国家不可能拥有真正的隐形飞机，更不可能对美军发起隐形攻击，因此反隐身雷达可有可无，并不重要。
美国认为自己独有隐身战机的优势，不需要反隐身雷达
和美军相反，中国一直饱受隐形飞机的威胁，并且对此有着切身之痛。能够探测隐身飞机的雷达，一直是中国国防科技研究的重中之重，而国内经过技术攻关，使用分区独立波束保型（波束多焦点）克服了第一和第三点问题，用MIMO加地形匹配数学模型加计算解决了测高问题。使得原本只能做二维预警雷达的米波雷达，可以做成相控阵的三维目标指示雷达，精度可以引导火控雷达和航空兵进行拦截，这是一个创举。
中国在珠海航展上公开展示的反隐身雷达
中国的歼20隐身战机面世之后，美国第一次感受到真正的威胁。于是不得不又重新捡起反隐身雷达这一概念，并且在尽力参考中国雷达的外形和技术指标之后，由洛克希德·马丁公司研制出TPY-X陆基远程多任务雷达系统。
歼20的出现迫使美军不得不认真考虑反隐身雷达的研制
不过，由于雷达频谱资源都是国家统一管理的，像wifi用的2.4G，未来5G用那些频段都是国家规定的一样，别的设备不能用，不然会产生严重干扰。所以现在即使美国想用，也会发生和别的设备产生严重干扰问题，技术虽已实现，但是要实战部署却不是那么容易的事。（作者署名：铁翼苍穹）

F-22
自美国成为世界上第一个拥有隐身战机的国家后，世界其他国家对于隐身战机也是心升向往。但由于技术等原因，截止到目前，也就是只有中美俄三个国家具备了自主研发隐身战机的能力。而近日，美国媒体却发表一篇文章表示，F-35、F-22正面临一项挑战，让其能被轻易击落，即使是备受期待的隐身技能也无法解决这个问题。
一直以来隐身战机就被认为是各种武器当中，技术含量最高的一种。但实际上它并不是无敌的存在，美国媒体在近日撰文表示，有一项对F-22、F-35的挑战，似乎不会动摇，即使是隐身也不能解决这个问题。
那就是对隐身战机和非隐身战机来说，它们必须在敌人弹道导弹和巡洋导弹的射程内部署其航空母舰和空军基地，因为“短腿”的问题，目前美国已经投入了数十亿到隐身战机的研究制造当中，但这种情况的出现，将有可能让这数十亿美元最终打水漂。
歼-20
作为21世纪空战的关键，F-22的短腿问题也遗传到了F-35身上，而打造一架隐身加油机对于美军来说，似乎还有点荒谬，所以以现在美军的状况来说，这让其在未来的空战中略微处于弱势，有趣的是同样的问题，对于歼-20战机来说，似乎并没有。
根本原因就在于，歼-20近5000公里的最大航程几乎是F-22约2963公里和F-35约2220公里的两倍，这也意味着，歼-20的滞空时间将被它们更长，即使同样配备加油机的情况下，歼-20被暴露的风险也要比F-22、F-35要小的多，而这也是歼-20对比F-22、F-35的优势之一。
对此，网上有部分美国网友对此表示，“或许就是因为这个原因，美军复制了一架歼-20，进行研究。”在今年12月的时候，一架疑似中国歼-20的战机，出现在了美国的乔治亚机场，由于太出乎意料，当时人们对这张照片的真假进行了激烈的讨论，但经过网友的仔细辨认，这张照片应该是真的 。
对比照片
据悉网友将这张照片的背景和乔治亚机场的卫星照片进行了对照，发现两者似乎是完全相同的，这也更加确定了这张照片的真实性。因此我们也可以猜测，这架歼-20可能是美国为了研究中国的隐身战机，而做出了一个等比模型。
从美国媒体最近的这篇报道我们也可以推测，也许美国复制出的这架等比模型，真的如美国网友猜测的那样，是为了解决F-22以及F-35的“短腿”问题呢。毕竟以三款战机相差不是非常大的重量，歼-20的航程却达到了美国隐身战机的2倍，这确实是一件让美国人诧异的事情。
所以复制一件歼-20的模型，了解这中国的气动布局，各种设计是很必要的。只是光从外形看，那架歼-20的模型，不仅做工粗糙，整体比例也不协调。毕竟这世界上“中国”只有一个，美国并不能像中国一样，拥有着“看一眼就会怀孕”的能力。（作者署名：前沿哨所 智忠）

A few days ago, the network exposed two news, very interesting. First, Wu Jianqi, the chief scientist of the China Electronics Group, publicly made a domestic report on the anti-stealing advanced meter wave radar, saying that the F22 was detected for the first time in 2013 and the flight path was drawn. At that time, other radars did not find the target.

Secondly, on December 13, Lockheed Martin of the United States publicly demonstrated a prototype of the newly developed TPY-X land-based remote multi-role radar system, whether it is the shape of the radar antenna, the technical system, the functional use description, and 2014 At the 10th Zhuhai Air Show in November, the JY-26 Mibo anti-stealth phased array radar system exhibited by Chinese military workers was the same! Today we will talk about these two things.

Is the prototype of the US TPY-X land-based long-range multi-role radar system similar to China? Is the prototype of the US TPY-X land-based long-range multi-role radar system similar to China?
A long time ago, there were rumors in the military circle that China had detected the US F22 stealth fighters, and even had the news of shooting down the F22 or F22. Since then, there has been a new version of the legend almost every year. It seems that today there is no wind and no waves. (Of course, shooting down F22 or F22 to defect, in fact, is that China has made a feature recognition model of the US military's fifth-generation aircraft, which was just captured by satellite.) According to Wu Jianqi’s chief engineer, China was the first to successfully develop and deploy Mibo The country of stealth radar. The meter wave radar has three major defects: the low elevation angle blind area is large, the specular reflection occurs at a certain angle below the certain angle, the height measurement cannot be accurately performed, and the air space coverage is discontinuous.
The middle of the 052C destroyer hull is a typical Mibo anti-stealth radar 052C destroyer hull is a typical Mibo anti-stealth radar
In fact, before the United States, the United States and Russia had already begun to pre-study the meter wave radar, but because they could not overcome the three major defects mentioned above, they thought it was impossible to give up. More importantly, the United States has always believed that in the foreseeable time, other countries cannot have a true stealth aircraft, and it is even less likely to launch an invisible attack on the US military. Therefore, anti-stealth radar is optional and not important.
The United States believes that its unique stealth fighter advantage does not require anti-stealth radar. The United States believes that its unique stealth fighter advantage does not require anti-stealth radar.
Contrary to the US military, China has always been threatened by stealth aircraft and has a personal pain. The ability to detect stealth aircraft radar has always been the top priority of China's national defense science and technology research, and domestically, through technical research, using partitioned independent beam protection (beam multi-focus) to overcome the first and third problems, using MIMO plus terrain The matching mathematical model plus calculation solves the altimetry problem. The meter wave radar, which can only be used as a two-dimensional early warning radar, can be used as a phased array 3D target indicating radar. The precision can guide the fire control radar and the aviation to intercept. This is a pioneering work.

After China’s 歼20 stealth fighters were launched, the United States felt the real threat for the first time. Therefore, the concept of anti-stealth radar has to be revived, and after trying to refer to the shape and technical indicators of China's radar, Lockheed Martin developed the TPY-X land-based long-range multi-tasking radar system.
The emergence of 歼20 forced the US military to seriously consider the development of anti-stealth radar. The emergence of 歼20 forced the US military to seriously consider the development of anti-stealth radar.
However, since the radar spectrum resources are uniformly managed by the state, 2.4G like wifi, the future 5G uses those frequency bands that are prescribed by the state, and other devices cannot be used, otherwise it will cause serious interference. So now even if the United States wants to use it, it will cause serious interference problems with other equipment. Although the technology has been realized, it is not so easy to deploy in actual combat. (Author's signature: Iron Wing)

F-22
Since the United States became the first country in the world to have stealth fighters, the rest of the world is also eager for stealth fighters. However, due to technical reasons, until now, only three countries in China, the United States and Russia have the ability to independently develop stealth fighters. Recently, the US media published an article saying that the F-35 and F-22 are facing a challenge that can be easily shot down. Even the highly anticipated stealth skills cannot solve this problem.
Stealth fighters have long been considered to be among the most technically diverse. But in fact it is not an invincible existence. The American media recently wrote that there is a challenge to the F-22 and F-35 that does not seem to be shaken. Even stealth cannot solve this problem.
That is, for stealth and non-stealth fighters, they must deploy their aircraft carriers and air bases within the range of enemy ballistic missiles and cruise missiles. Because of the "short leg" problem, the United States has invested billions to stealth. The research and manufacture of fighters, but the emergence of this situation, will likely make these billions of dollars eventually squander.
歼-20
As the key to the 21st century air battle, the short leg problem of the F-22 was also inherited to the F-35, and it seems a bit ridiculous for the US military to build a stealth tanker. So in the current situation of the US military, this makes It is slightly weak in the future air combat, and the same is interesting. For the J-20 fighter, it does not seem to be.
The root cause is that the maximum range of 歼-20 nearly 5,000 kilometers is almost 2,963 kilometers for F-22 and 2,220 kilometers for F-35, which means that the stagnation time of 歼-20 will be longer. Even with the same tanker, the risk of exposure to the 歼-20 is much smaller than that of the F-22 and F-35, and this is one of the advantages of the 歼-20 versus the F-22 and F-35.
In response, some US netizens on the Internet said, "Maybe for this reason, the US military copied a 歼-20 to conduct research." In December of this year, a suspected Chinese 歼-20 fighter appeared. At the Georgia airport in the United States, because it was too unexpected, people had a heated discussion about the true and false of this photo, but after careful identification by netizens, this photo should be true.
Compare photos
It is reported that the netizen compared the background of this photo with the satellite photos of Georgia Airport and found that the two seem to be identical, which further confirms the authenticity of this photo. Therefore, we can also speculate that this 歼-20 may be an analogy model for the United States to study China's stealth fighters.
From the recent report of the US media, we can also speculate that perhaps the equivalent model copied by the United States is really the same as the US netizens guessed to solve the "short leg" problem of the F-22 and F-35. . After all, the difference between the three fighters is not very large, and the voyage of the 歼-20 has doubled that of the stealth fighters in the United States. This is indeed a thing that makes Americans surprised.
So copying a model of the 歼-20 to understand the aerodynamic layout of China, various designs are necessary. Just the light looks from the shape, the model of the 歼-20 is not only rough in work, but the overall proportion is not coordinated. After all, there is only one "China" in the world. The United States cannot have the ability to "seek at a glance" like China. (Author's signature: Frontier Posts Zhizhong)
