Original title: the successful development of the country’s first microwave photon radar
China Electronics Research Institute successfully developed the first domestic radar prototype based on microwave photonic technology, and the inverse synthetic aperture imaging test of the non cooperative target field, the first domestic microwave photon radar imaging pattern,Pushednew techniqueDevelopment of new radar research.FirsttinyLidarBistatic radar system and photon are adoptedFrameworkThe RF front-end at the transmitter and receiver is introduced separatelyRadar signals, microwave photon generation, anddechirpReceiving technology,Able to support broadband workHas the promotionRange resolution potential.Image resolution obtained from an external fieldCompared to the internationally reported similar microwave photonic radar, it has been improved by an order of magnitude, and the image sharpness has also been greatly improved.
Microwave photonic radar research is a multidisciplinary field which combines microwave photonic technology and radar technology, and is one of the key directions for the research of new technology and system radar. Study on photonic microwave radar, based on the electronic Institute, the Chinese Academy of science and technology innovation project of Chinese Academy of Sciences, the first action key deployment plan, microwave radar technology to verify the photon imaging test platform for repair and purchase items and electronic support; with the introduction of microwave photonics background of thousands of overseas young researcher Li Wangzhe and Li Ruoming into the work, combined with the the electronic radar technology of professional strength and research experience, through the collision between families of integration, technical personnel exchanges and cooperation between different professional students, effectively promote the development of photonic microwave radar. fromThe second half of 2015, the relevant professional team collaborative innovation, has completed the design of microwave photon imaging demonstration, photon radar system of wideband radar signal generation and photon to FM receiving such key technologies and related imaging algorithm research. After the laboratory principle verification, the darkroom target imaging experiment and the system integration, the imaging test of the non cooperative target in the outfield has been realized successfullyThe microwave photon radar is verifiedfeasibility. The research results have been published in the International Journal of OpticsOptics Express) receive, be about to publish.
In the outfield test, including Boeing737 aircraft, including different models, different distances and different angles of view, were imaged. Thanks to the microwave photon radar architecture, unique advantages, and photonic technology in broadband signal processing system and spurious suppression of the microwave photon radar imaging image can clearly identify the target structure details, such as aircraft engines, empennage and flap guide rail structure, showing the ability of radar target identification of microwave photonic structure compared with the results of field imaging, published in the journal “nature” on the microwave photon radar system has been done, as shown in Figure 2, the electronic microwave photon radar imaging results are significantly improved. Next, the research work in this direction will be further improvedMicrowave photon radarImaging performanceAnd continue to explore the application value of microwave photonic technology in different radar systems.
The first part of the successful development of domestic microwave photon radar prototype to fill the domestic blank in this field, promote the system with the traditional microwave photonic technology especially the fusion of the radar system, marking the future of radar technology and system of the new stage of development, lay the foundation for the birth of the future new system of radar system.
