原标题：我国微波光子雷达成像分辨技术已达国际领先
科技日报4月27日消息，“我们已经研制出微波光子雷达成像芯片，像砂粒一样小，比传统雷达设备小一万倍。它不仅可用于安全领域，在无人驾驶汽车等也可以大展身手。”4月27日，在2019全国微波光子雷达技术研讨会上，南京航空航天大学电子信息工程学院副院长、雷达成像与微波光子技术教育部重点实验室副主任潘时龙告诉记者，我国在微波光子雷达部分技术领域已取得较大进展，成像雷达分辨率达1.3厘米，已领先其他国家。
微波光子技术被美、俄、欧认为是决定“未来战场优势”的关键技术。微波光子学是利用光子技术完成微波、毫米波、THz波系统中复杂甚至是无法完成的信号产生、处理、传输与控制等功能。
微波光子雷达利用光子技术，能够有效提升雷达系统的目标分辨率、作用距离、响应速度等关键性能，有助于实现侦察、干扰、探测、通信的一体化。
对低空飞行的小型无人机实时成像动图
“微波光子雷达带宽大，可支持多频段、多信号协同工作，实现高分辨率成像、多目标识别和低RCS目标探测。同时，可以显著提升信噪比和改善因子，大大改善强杂波中微弱信号的检测能力。可以产生和处理适应各种复杂环境的信号波形，拓展了信号自由度。” 中国工程院院士、南航电子信息工程学院院长贲德认为其优势明显，“比如1千兆到100千兆是微波光子雷达工作的频段，现有雷达对这个频段显得有些无能为力。”
目前，美国、俄罗斯、欧盟等都在开展实用化微波光子雷达相关的研究。在我国，以中国科学院、南京航空航天大学为代表，诸多高校和研究所均开展了一系列的关键技术攻关和探索。已经初步掌握了光子任意波形产生技术、超宽带信号光子采集技术、超宽带信号光子波束控制技术、超宽带信号光子处理技术等微波光子雷达的初步技术。
本次研讨会邀请了国内微波光子雷达领域17位著名专家，就光子技术在雷达领域的应用做特邀报告，共同探讨微波光子技术如何进一步促进雷达发展升级。

China's microwave photon radar imaging leads the world, determining the future battlefield advantage

Original title: China's microwave photon radar imaging resolution technology has reached the international lead
Science and Technology Daily reported on April 27th, "We have developed a microwave photon radar imaging chip that is as small as sand and is 10,000 times smaller than conventional radar equipment. It can be used not only in the security field, but also in driverless cars. "On April 27th, at the 2019 National Microwave Photonic Radar Technology Seminar, Pan Shilong, deputy dean of the School of Electronics and Information Engineering of Nanjing University of Aeronautics and Astronautics and the deputy director of the Ministry of Education of Radar Imaging and Microwave Photonics Technology, told reporters that China is Microwave photonic radar has made great progress in the technical field. The imaging radar has a resolution of 1.3 cm and is already ahead of other countries.
Microwave photon technology is considered by the United States, Russia, and Europe as the key technology to determine the "future battlefield advantage." Microwave photonics is a photon technology that performs complex, even incomplete, signal generation, processing, transmission, and control functions in microwave, millimeter-wave, and THz wave systems.
Microwave photonic radar can effectively improve the target performance, range and response speed of the radar system by using photon technology, which is helpful for the integration of reconnaissance, interference, detection and communication.
Real-time imaging of small unmanned aerial vehicles with low-altitude real-time imaging
"Microwave photonic radar has large bandwidth and can support multi-band and multi-signal cooperation to achieve high-resolution imaging, multi-target recognition and low RCS target detection. At the same time, it can significantly improve the signal-to-noise ratio and improvement factor, and greatly improve the strong clutter. The ability to detect weak signals can generate and process signal waveforms that adapt to various complex environments and expand the degree of freedom of signals.” Yan De, an academician of the Chinese Academy of Engineering and dean of the School of Electronic Information Engineering of China Southern Airlines, believes that its advantages are obvious, “such as 1 Gigabit to 100 Gigabit is the frequency band in which microwave photon radars work. Existing radars seem to be incapable of doing to this band."
At present, the United States, Russia, the European Union, etc. are conducting research related to practical microwave photonic radar. In China, represented by the Chinese Academy of Sciences and Nanjing Aerospace University, many universities and research institutes have carried out a series of key technical research and exploration. The preliminary techniques of photon arbitrary waveform generation technology, ultra-wideband signal photon acquisition technology, ultra-wideband signal photon beam control technology, ultra-wideband signal photon processing technology and other microwave photon radars have been mastered.
This seminar invited 17 famous experts in the field of microwave photon radar to make a special report on the application of photon technology in the radar field, and jointly explore how microwave photonic technology can further promote the development and upgrade of radar.
