What is the birth of China's first microwave photon radar?

Recently, I successfully developed the first microwave photon radar prototype in China through the Chinese Academy of Sciences. This mine adopts the two station radar system and photon architecture, which can support broadband work and has the potential to improve the range resolution. Now let's see the details!

The Institute of electronics, Chinese Academy of Sciences has successfully developed the first radar prototype based on microwave photon technology in China, and has carried out the inverse synthetic aperture imaging test of non cooperative targets in the field, obtained the first microwave photon radar imaging pattern in China, and promoted the development of new technology and new system radar research. The first microwave photon radar adopts the two station radar system and photon architecture, and introduces the microwave photon generation and de frequency modulation reception technology in the RF front-end of transmitter and receiver respectively, which can support the broadband work and has the potential to improve the range resolution. The image resolution obtained in the field is one order of magnitude higher than that of the same kind of microwave photon radar reported in the world.

Microwave photon radar research is a multi-disciplinary interdisciplinary field which combines microwave photon technology and radar technology. It is one of the key cultivation directions for the research of new technology and new system radar of Institute of electronics. The research of microwave photon radar is based on the first office of the Institute of electronics, supported by the key deployment project of scientific and technological innovation of the Chinese Academy of Sciences, the first action plan of the Chinese Academy of Sciences, and the repair and purchase project of microwave photon imaging radar technology verification and testing platform. At the same time, the Institute of Electronics introduced overseas young researchers with the background of microwave photonics, Li wangzhe and Li Ruoming, into the Institute to carry out their work, in combination with the Institute of electronics, Lei The professional strength and research experience in technology have greatly promoted the development of microwave photon radar research through collision and fusion among different disciplines and exchange and cooperation between different professional and technical personnel. Since the second half of 2015, relevant professional teams have cooperated and innovated, and successively completed the design demonstration of microwave photon imaging radar system, photon generation of wideband radar signal, photon de modulation reception and other key technology research and development of relevant imaging algorithms. After the laboratory principle verification, darkroom point target imaging experiment and system integration joint debugging, the imaging test of non cooperative targets in the field is finally realized, and the feasibility of the microwave photon radar is successfully verified. The research results have been received by the international journal Optics Express and will be published soon.

In this outfield test, imaging tests were carried out for different aircraft types, different distances and different perspectives, including Boeing 737. Thanks to the microwave photon radar architecture and the unique advantages of photon technology in broadband signal generation, processing and system spurious suppression, the imaging image of microwave photon radar can clearly identify the structural details of the target, such as aircraft engine, tail, flap guide rail and other structures, showing the recognition ability of microwave photon radar for the structural characteristics of the target, and comparative publishing As shown in Figure 2, the imaging results of the microwave photon radar system of the Institute of electronics have improved significantly. Next, the research work in this field will further improve the imaging performance of microwave photon radar, and continue to explore the application value of microwave photon technology in different radar systems.

The first prototype of the domestic microwave photonic radar successfully fills the gap in the field of research in China, and promotes simultaneous interpreting of photonic technology with traditional microwave systems, especially radar systems. It marks the new development stage of radar technology and system in the future, laying the foundation for the birth of the new body radar system in the future.
