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.
