Spectrum resource shortages are expected due to the high capacity and speed of communication for extreme coverage in Beyond 5G. Meanwhile, allocating efficient, adaptive operations and ensuring new spectrum opportunities cannot be achieved owing to static and exclusive conventional spectrum management. To address this problem, dynamic spectrum access (DSA) has been proposed and DSA can perform varied spectrum control via spectrum sensing. However, expanding the DSA application area is difficult since wide area and real-time spectrum recognition cannot be obtained using conventional spectrum estimation methods. We proposed a new spectrum sensing by Low Earth Orbit (LEO) satellite constellation, placing the same satellites in a straight track based on Synthetic Aperture Radar (SAR) processing for spacial resolution improvement (See more).
