An Improved Hybrid Beamforming Algorithm for Fast Target Tracking in Satellite and V2X Communication
Publikováno v:
Remote Sensing, Vol 16, Iss 1, p 13 (2023)
Autonomous remote sensing systems establish communication links between nodes. Ensuring coverage and seamless communication in highly dense environments is not a trivial task as localization, separation, and tracking of targets, as well as interferen
