Abstract:

Zhongyu Li is the winner of 2022 URSI Young Scientists Award, and also the Outstanding Doctoral Society Award of the Chinese Institute of Electronics, and he was successfully selected for the China Postdoctoral Innovative Talent Support Program. He received the B.S. and Ph.D. degrees in Electronic Engineering from the University of Electronic Science and Technology of China (UESTC), Chengdu, China, in 2011 and 2017, respectively. From 2015 to 2016, he was a visiting Ph.D. student with the Department of Information Engineering, Electronics and Telecommunications, Sapienza University of Rome, Rome, Italy. He is currently an associate professor with UESTC. His research interests include synthetic aperture radar technology (particular emphasis on bistatic/multi-static SAR moving target detection and imaging technologies). He has published more than 60 journal and conference papers. He received the “Excellent Paper Award - First Prize” at the 2019 6th Asia-Pacific Conference on Synthetic Aperture Radar. He was the TPC member of 2020 IEEE Radar Conference, 2019 APSAR, and the section chair of the 2021 CIE International Conference on Radar, 2020-2021 IEEE ICET, ALLSENSORS 2019, and 2020 ICCC. He served on the editorial boards of the ‘Modern Radar’ and ‘Radar Science and Technology’, and served as the guest/topic editors of ‘Remote Sensing’ and ‘Frontiers in Signal Processing’.


Brief biography:

This report focuses on the passive radar vessel target detection using BeiDou navigations satellites as opportunistic sources. The detection method and the first experimental results are given in this report. Compared with the active radar, the lack of dedicated transmitters reduces the cost of passive radar. Its bi-/multi-static configuration offers the capabilities of anti-stealth and anti-jamming. From a passive radar perspective, BeiDou constellation is particularly attractive since it provides the potential for persistent monitoring anywhere in the world, including the poles. And any point is simultaneously illuminated by 4-8 BeiDou satellites from different angles. Thus, vessel target detection is potentially achieved using BeiDou-based passive radar. The fundamental limitation in BeiDou-based passive radar is its extremely low power density near the Earth’s surface, and it is necessary to propose innovative vessel target detection methods for the system under consideration.
