刘永坦院士获得2018年度国家最高科学技术奖，其新体制雷达有何不凡！刘永坦院士瞄准美国最高保密的ISAR（逆合成孔径雷达），自行突破，因为美国对原理和雷达外形高度保密，估计中国ISAR雷达应该与美国技术不同，但殊途同归，效果一样。
让F22无处遁形！中国反隐身雷达车可拖着全国跑1/5
查看原图图集模式
反隐身雷达CCTV2播放14所的采访，有半个小时，央视曝光中电14所反隐雷达相当于三室两厅两卫那么大，一部雷达车拖着全国跑，随处布阵，让F22无处遁形。中国电科第十四研究所与共和国同龄，是目前亚洲第一大雷达研究所，国家诸多新型、高端雷达装备的始创者，被业界誉为中国雷达工业的发源地。节目结尾用了这么几句话：“陆海空天四维一体、始终保持领先、不被竞争对手占据先机”。这是说这款雷达是全球第一水平啊！
本文图片均是美国同类雷达成像效果 ，中国的尚未公布，因为保密级别太高。
猛禽应无恙，当惊世界殊
F-22猛禽在新体制雷达上的成像图
其实美国早在七十年代测试过ISAR雷达，发现上可以探测太空4 万公里高空的卫星和太空碎片，当时美还趁机测试出了中国东方红一号卫星的大小和形状。后来美军把当时世界名机全部用新雷达测试了一遍，看看F22在新体制雷达上成像，外观效果清晰易认，猛禽无路可逃！
合成孔径雷达只能对静止目标，如大地目标三维探测。ISAR（逆合成孔径雷达）则相反，对动目标或者非合作目标不可预测的目标效果相当好 ，采取敌动我不动，利用回波信号进行数字分析和自动补偿，得到目标的二维和三维形状信息，可自动识别目标。美军分别对F-22、欧洲台风战斗机、米格-29、F-104战斗机进行过ISAR（逆合成孔径雷达）成像测试，效果惊人。
美军ISAR（逆合成孔径雷达）一般精度可达0.12米，最高可达3厘米级别。
自动识别航母和货轮
同时，ISAR（逆合成孔径雷达）还可对海上目标远程测试，尤其是对航母识别率非常高。航母体积大，但航母编队在太空卫星眼里，就是一个小点，很难识别。但ISAR（逆合成孔径雷达）可以清晰看到航母三维形态，是货轮还是航母，一目了然。
ISAR（逆合成孔径雷达）成像测试
ISAR（逆合成孔径雷达），核心技术是算法很重要，全世界可能就中美俄三国掌握，其他很少有听说。美国最新航空母舰，也装备了这种逆合成孔径雷达多模，强化电子打击能力。
根据官方报道，中国第一台ISAR（逆合成孔径雷达）试验平台在山东，九十年代初就实验成功探测到飞机舰船，然后97年国家立项，再经十余年才技术成熟，装备沿海一线。
ISAR（逆合成孔径雷达）和米波反隐雷达有什么不同？
美国ISAR雷达
简单来说，一个是远程战略预警雷达，海空通吃，精度高达0.12米，从太空卫星到海上飞机导弹都能探测，包括隐形飞机；而米波反隐雷达则是战术雷达，主要给一线部队实战所用的防空雷达，距离和探测有限，不是全能型。（作者署名：蜀中行讲武堂）

什么叫新体制超视雷达？
ISAR（逆合成孔径雷达）成像
新体制超视雷达，实际就是国际顶尖的ISAR（逆合成孔径雷达）。合成孔径雷达，全世界能掌握的就那么几个国家，已经很困难了。俗话说，顺为凡，逆天仙。逆合成孔径雷达，反其道而行之，有多牛呢？可以看清数千公乃至数万空里内的目标，海空通吃，目标精度可达0.12米左右，而且是实时二维或三维成像，能看清歼十的鸭翼和几千公里外的空中飞鸟，非常直观。普通雷达目标只是一个光标，目标的型号信息很难判断，逆合成孔径雷达相当于看数千公里外的照片，一目了然。
美国ISAR（逆合成孔径雷达）成像精度
ISAR（逆合成孔径雷达）美国在上世纪六十年代理论突破，然后在七十年代开始实验装备，发现效果好得惊人，可以看清40000公里外的太空目标三维信息，大喜过望。美国人发现ISAR能极大地提高了对空间弱小目标的成像能力，从而具备跟踪太空垃圾和空间碎片的能力。美国的ISAR（逆合成孔径雷达）达于1970年1月起在夸贾林靶场投入使用，同年对中国第一颗人造卫星“东方红1号”的火箭进行了跟踪和成像，推算得到长征火箭的尺寸和运载能力，从而推断出卫星的尺寸信息。现在美军相关ISAR（逆合成孔径雷达）可对弹道导弹目标进行实时成像，并能精确估计出真假弹头因目标质量不平衡导致的运动差异。美军最新的新体制超视距雷达，工作在X波段，距离分辨率可达0.0187m。
美国ISAR（逆合成孔径雷达）成像精度
在美军在七十年代突破之后，刘永坦在上世纪八十年代跟上研究，由于美国一直保密，雷达形状和技术原理一直保密，中国要突破非常困难。但刘永坦在八十年代就取得了理论突破，雷达试验大获成功，然后国家在1997年为新体制雷达批准正式立项，哈工大作为总体单位承担研制工作。经历10余年的艰辛努力和刻苦攻关，刘永坦和他的团队圆满完成了任务，打破了国外技术垄断，使中国成为世界上少数几个拥有ISAR（逆合成孔径雷达）技术的国家。作为国家总体军事战略中的一个重要组成部分，ISAR（逆合成孔径雷达）将在保卫祖国海疆的过程中发挥不可替代的强大作用。这一成果于2015年荣获了国家科技进步一等奖。
中国的ISAR（逆合成孔径雷达）技术现在处于什么水平，相信肯定是国际一流，与美国不相上下。
ISAR（逆合成孔径雷达）技术原理
ISAR（逆合成孔径雷达）成像
逆合成孔径是指雷达天线不动，被观测目标移动，对移动中的目标回波进行相干处理获得大的合成孔径，从而得到高方位尺寸分辨率，逆合成孔径的基础是转台成象。
逆合成孔径雷达，其成像可以获得反映目标大小、形状、结构及姿态等细节信息的二维及三维高分辨雷达图像，是解决目标识别问题的一种重要技术手段。
虽然ISAR和合成孔径雷达一样是利用雷达和目标间的相对运动成像的，但是，SAR在运动平台上对固定目标和场景进行成像，其自身运动规律是可知或基本可知的，而ISAR一般针对非合作目标进行成像，其自身运动的不确定给运动补偿带来了困难。
逆合成孔径雷达作为一种新体制雷达，能够对飞机、导弹、舰船、卫星等运动目标进行高分辨二维成像，在战略防御、战术武器、反卫星等军事领域以及未来的空中、空间交通管制等民事领域中都有重要的应用价值。
ISAR（逆合成孔径雷达）成像
刘永坦在新体制对海探测雷达的研制工作中，突破了11项关键技术，解决了在强海杂波、电台干扰及大气噪声背景下的信号处理和目标检测问题。在逆合成孔径雷达研究中，掌握运动补偿理论，在数字式宽带FM/CW雷达信号处理机的研制中，解决了大动态宽频信号高分辨谱分析问题。
ISAR（逆合成孔径雷达）成像
刘永坦于1982年至1985年期间主持航天部预研项目“新体制雷达关键技术及方案论证”，其关键技术突破为我国新体制雷达研制成功打下了基础。1986年至1990年，刘永坦主持了国防科工委国防科技应用与基础研究项目“新体制雷达研究”。他综合关键技术成果，研制成完整的雷达系统，并于1990年建成了我国第一个高频新体制雷达站，成功地探测和跟踪了舰船和飞机目标，其技术指标达到了90年代国际先进水平。该项目于1991年获国家科技进步一等奖。1987至1995年他主持863计划中“逆合成孔径实验雷达”（即ISAR）重大项目的研究工作，历经五年攻关，研制成我国第一台实验ISAR，通过进行大量外场实验，录取了大量珍贵的数据，并成功的完成对飞机目标的雷达成像，达到国际90年代先进水平，1997年获国家科技进步二等奖。
纵观ISAR成像雷达系统和技术的发展历程，可以看出：ISAR雷达探测在提高目标轨道信息获取能力的同时，更加注重获取目标的电磁散射特性，实现了空间碎片等微小目标、同步轨道卫星等超远距离目标的宽带高分辨成像观测。
ISAR（逆合成孔径雷达）成像
ISAR成像雷达将围绕超远距离探测和高分辨精细成像两大技术主题快速展开，而高分辨精细成像在实现目标检测和准确识别中显得尤为重要。
在新体制雷达装备前，中国只能对20%的海空监视，而装备之后，可以实现100%海空全时覆盖，还能对数千公里外的目标，不论是太空卫星，还是海上航母，或者是隐形飞机，实时成像探测，精度可靠，真正的战略利器。（作者署名：蜀中行讲武堂）

刘永坦为何获最高科技奖 其成果让美隐身舰无所遁形
刘永坦为何获最高科技奖 其成果让美隐身舰无所遁形

对于从事在科学研究一线的我国科研工作人员而言，一年一度的国家最高科学技术奖，毫无疑问代表着该领域的最高荣誉。在这当中，与国家安全密切相关的国防科技领域，始终是该奖项的夺魁热门。正是得益于该奖项极高的含金量，几乎每年获奖得主的公开，都能给关心国防科技建设的军迷们带来巨大的惊喜。在刚刚揭晓的2018年度国家最高科学技术奖的两位得主中，已经年过八旬的雷达专家刘永坦院士，就凭借着一款神奇的新体制雷达，荣膺了这个让无数科研工作人员梦寐以求的奖项。
荣膺2018年国家最高科学技术奖的雷达专家刘永坦院士
“坚持自主研发新体制雷达，打破国外技术垄断，为我国海域监控面积的全覆盖提供技术手段”——以上就是官方对刘永坦院士的获奖描述。实际上，从这段描述中，相信大多数人都已经猜到了，这款新体制雷达主要的定位是对海监视。不过，相比那些受地球曲率影响，有效探测距离不过数十千米的传统对海搜索雷达，由刘永坦院士主持研发的新体制雷达，却能无视地球曲率，做到对数百千米外水面目标的有效探测和跟踪。如此远的作用距离，足以覆盖我国大部分海域与专属经济区，可谓名副其实的“海疆千里眼”。
图为2009年设置在威海的测试雷达高频收发天线
这款被誉为“海疆千里眼”的新体制雷达之所以能无视地球曲率，这其中关键正是不太为人所知的“高频地波超视距”概念。相比于传统微波雷达电磁波以直线传播的特性，新体制也就是高频地波超视距雷达，由于利用了高频波段的电磁波能够在洋面形成表面波传导的特性，因此可以依托洋面对地平线以下的水面目标进行有效的监视，达成超视距探测的效果。也正是因为高频地波超视距雷达的这种特殊能力，包括我国在内的许多国家，都十分重视这类新体制雷达的发展，并纷纷以此为基础打造出了十分有效的对海超视距监视系统。
地波超视距雷达的原理使其可以具备超视距探测能力
值得一提的是，这种高频地波超视距雷达除了具备超视距、远距离、抗干扰等一系列优势外。得益于相比传统微波雷达更长的工作波长，他们对采用了隐身设计的水面舰艇、以及以超低空方式突防的巡航导弹甚至隐身飞机等目标，均有着十分优秀的预警探测能力。在很大程度上讲，新体制雷达对于DDG-1000这类主要活动在他国濒海地区的隐身水面舰艇，基本上可以做到使其无所遁形。如果说我们熟知的米波反隐身雷达是针对隐身战机探测的利器，那高频地波超视距雷达，毫无疑问的属于面向海防领域的反隐身神器。
新体制雷达可以让DDG-1000这类隐身舰艇无所遁形
尽管在我们所津津乐道的弹道导弹反航母体系中，高频地波超视距雷达的有效作用距离尚不如舰载机作战半径，也不能如同天波超视距雷达一般拥有动辄数千公里的探测能力，但这并不意味着高频地波超视距雷达的重要性不如天波超视距雷达。恰恰相反，由于天波超视距雷达的特殊体制，必然存在长达数百千米的近距盲区，使其无法对沿海地区形成有效覆盖，而作用距离达数百千米远的高频地波超视距雷达，正是用于覆盖这个区域的首选。从这个角度上讲，两者属于优势互补的关系，都是构成我国对海超视距监视的重要组成部分。
地波超视距与天波超视距都是我国对海监控的重要组成部分
近些年来，我国很低调的推进了多个战略性质的雷达探测网络的建设，除了本文中提及的地波雷达和天波雷达外，还有针对空中目标的反隐身米波雷达和弹道导弹探测雷达网络。这些系统的建设，基本完成了我国各个重点方向上战略预警网络组网，对于我国的国防安全来说有着极为重要的意义。（作者署名：啮花熊）

The national treasure academician broke through the new radar technology and clearly outlined the F22 shape (Figure)
January 09, 2019 11:14 Sina Military

F22
Academician Liu Yongtan won the National Science and Technology Award of 2018, and his new system radar is extraordinary! Academician Liu Yongtan aimed at the highest-secure ISAR (Inverse Synthetic Aperture Radar) in the United States and made a breakthrough on his own. Because the United States is highly secretive about the principle and radar shape, it is estimated that China's ISAR radar should be different from American technology, but the same goal is the same.
Let the F22 nowhere! China's anti-stealth radar can drag the country to run 1/5
View the original map mode
Anti-stealth radar CCTV2 broadcast 14 interviews, half an hour, CCTV exposure CLP 14 anti-implicit radar is equivalent to three rooms, two halls and two guards, a radar car dragging the country to run, everywhere to make F22 no At the shape of a skull. The 14th Research Institute of China Electric Power is the same age as the Republic. It is currently the largest radar research institute in Asia. The founder of many new and high-end radar equipments in the country has been hailed as the birthplace of China's radar industry. At the end of the program, I used a few words: "The land, the sea, the sky, the sky, the four-dimensional integration, always stay ahead, not to be taken advantage of by competitors." This is to say that this radar is the world's first level!
The pictures in this article are all similar radar imaging effects in the United States, and China has not yet announced it because the level of confidentiality is too high.
Raptor should be innocent, when the world is shocked
Imaging image of F-22 Raptor on the new system radar
In fact, the United States tested the ISAR radar in the 1970s and found that it could detect satellites and space debris at an altitude of 40,000 kilometers. At that time, the United States also took the opportunity to test the size and shape of the China Eastern Red One satellite. Later, the US military tested all the world's famous machines with the new radar at that time, and saw that the F22 was imaged on the new system radar. The appearance was clear and easy to recognize, and the raptor had no way to escape!
Synthetic Aperture Radar can only detect three-dimensional objects on stationary targets, such as earth targets. ISAR (Inverse Synthetic Aperture Radar), on the other hand, works well for unpredictable targets or non-cooperative targets. I take the enemy and do not move, using echo signals for digital analysis and automatic compensation to obtain 2D and 3D targets. Shape information that automatically identifies the target. The US military conducted ISAR (Inverse Synthetic Aperture Radar) imaging tests on the F-22, the European Typhoon fighter, the MiG-29, and the F-104 fighter, respectively, with amazing results.
US Army ISAR (Inverse Synthetic Aperture Radar) generally has an accuracy of 0.12 meters and a maximum of 3 cm.
Automatic identification of aircraft carriers and freighters
At the same time, ISAR (Inverse Synthetic Aperture Radar) can also be used for remote testing of maritime targets, especially for aircraft carriers. The aircraft carrier is bulky, but the aircraft carrier formation in the space satellite eye is a small point that is difficult to identify. However, ISAR (Inverse Synthetic Aperture Radar) can clearly see the three-dimensional shape of the aircraft carrier, whether it is a cargo ship or an aircraft carrier, at a glance.
ISAR (Inverse Synthetic Aperture Radar) imaging test
ISAR (Inverse Synthetic Aperture Radar), the core technology is that the algorithm is very important. The whole world may be mastered by China, the United States and Russia, and few others have heard of it. The latest US aircraft carrier is also equipped with this reverse synthetic aperture radar multimode to enhance the electronic strike capability.
According to official reports, China's first ISAR (Inverse Synthetic Aperture Radar) test platform was in Shandong. In the early 1990s, it successfully detected aircraft ships, and then in 1997, the country was established. After more than ten years, the technology was mature and equipped with coastal equipment. A line.
What is the difference between ISAR (Inverse Synthetic Aperture Radar) and Mipo Anti-Implicit Radar?
US ISAR radar
To put it simply, one is a long-range strategic early-warning radar, which has an accuracy of up to 0.12 meters. It can be detected from space satellites to sea-to-air missiles, including stealth aircraft. The Mibo anti-invisible radar is a tactical radar, mainly for the first line. The air defense radar used by the troops in combat is limited in distance and detection and is not versatile. (Author's signature: 蜀中行讲武堂)

What is the new system of super-vision radar?
ISAR (Inverse Synthetic Aperture Radar) imaging
The new system of super-view radar is actually the world's top ISAR (Inverse Synthetic Aperture Radar). Synthetic Aperture Radar, which is available in just a few countries around the world, has been difficult. As the saying goes, Shun Weifan, against the heavenly fairy. Inverse Synthetic Aperture Radar, in the opposite direction, how many cows? You can see the targets in thousands of tens of thousands of tens of thousands of air, the sea and the air are all eaten, the target accuracy can reach 0.12 meters, and it is real-time two-dimensional or three-dimensional imaging, which can see the duck wings and thousands of kilometers away. The flying birds are very intuitive. The ordinary radar target is just a cursor, and the model information of the target is difficult to judge. The inverse synthetic aperture radar is equivalent to viewing photos thousands of kilometers away, at a glance.
US ISAR (Inverse Synthetic Aperture Radar) imaging accuracy
ISAR (Inverse Synthetic Aperture Radar) The United States made a theoretical breakthrough in the 1960s, and then began experimenting with equipment in the 1970s. It found that the effect was amazing, and it was possible to see the three-dimensional information of the space target 40,000 kilometers away. Americans have found that ISAR can greatly improve the ability to image small space targets, and thus have the ability to track space debris and space debris. The US ISAR (Inverse Synthetic Aperture Radar) was put into use at the Kwajalein shooting range in January 1970. In the same year, the rocket of the first artificial satellite "Dongfanghong 1" was tracked and imaged, and the Long March rocket was estimated. The size and carrying capacity of the satellite to infer the size information of the satellite. The US Army-related ISAR (Inverse Synthetic Aperture Radar) can now perform real-time imaging of ballistic missile targets and accurately estimate the difference in motion between true and false warheads due to target mass imbalance. The latest new system of the US military's over-the-horizon radar works in the X-band with a resolution of 0.0187m.

After the US military broke through in the 1970s, Liu Yongtan kept up with the research in the 1980s. Since the United States has been kept secret, the radar shape and technical principles have been kept secret, and it is very difficult for China to break through. However, Liu Yongtan achieved theoretical breakthroughs in the 1980s, and the radar test was a great success. Then the state approved the formal establishment of the new system radar in 1997, and Harbin Institute of Technology assumed the development work as the overall unit. After more than 10 years of hard work and hard work, Liu Yongtan and his team successfully completed their tasks and broke the monopoly of foreign technology, making China one of the few countries in the world with ISAR (Inverse Synthetic Aperture Radar) technology. As an important part of the country's overall military strategy, ISAR (Inverse Synthetic Aperture Radar) will play an irreplaceable role in the defense of the motherland. This achievement won the first prize of National Science and Technology Progress Award in 2015.
China's ISAR (Inverse Synthetic Aperture Radar) technology is now at what level, I believe it must be world-class, comparable to the United States.
ISAR (Inverse Synthetic Aperture Radar) technology principle
ISAR (Inverse Synthetic Aperture Radar) imaging
The inverse synthetic aperture means that the radar antenna does not move, the target is moved, and the moving target echo is coherently processed to obtain a large synthetic aperture, thereby obtaining a high azimuth resolution. The basis of the inverse synthetic aperture is the turntable imaging.
Inverse Synthetic Aperture Radar (SAR) can obtain two-dimensional and three-dimensional high-resolution radar images that reflect detailed information such as target size, shape, structure and attitude, and is an important technical means to solve the target recognition problem.
Although ISAR and synthetic aperture radar use the relative motion between the radar and the target to image, the SAR images the fixed target and the scene on the motion platform, and its own motion law is known or basically known, while the ISAR is generally aimed at The cooperation target is imaged, and the uncertainty of its own motion brings difficulties to motion compensation.
