Abstract

Integrated Sensing and Communications (ISAC) is gradually becoming one of the key technologies in B5G/6G systems. Compared with conventional ground cellular systems, unmanned aerial vehicles (UAVs), thanks to their controllable trajectory, have been viewed as a promising technique to provide flexible communication services and synthetic aperture radar (SAR) based sensing. This paper investigates the trajectory optimization for UAVs simultaneously functioning as SAR and communication nodes, aiming to minimize the propulsion power under the communication and sensing objectives. To solve the non-convex problem, we propose a trajectory planning algorithm, wherein the successive convex approximation and block coordinate descent methods are employed to convexify the problem. Simulation results reveal that the proposed trajectory planning algorithm reduces power consumption by 50%, compared to the shortest trajectory scheme.
