Given the absence of places to employ communication infrastructures, there are many coverage blind zones in maritime communication networks. Benefiting from the high flexibility and maneuverability, unmanned aerial vehicles (UAVs) have been proposed as a potential means of provide broadband maritime coverage for these blind zones. In this paper, a multi-UAV-enabled maritime communication model where UAVs are used is suggested provide the transmission service for maritime users. To enhance the effectiveness of the maritime communication systems, A problem for optimisation is formulated to maximize the minimum throughput required by all users by jointly optimizing the user association, power allocation, and UAV trajectory. To derive the solutions with a low computational complexity, we Break this issue down into three subproblems, namely user association optimization, power allocation optimization, and UAV trajectory optimization. Then, a joint iterative algorithm is developed to achieve the solutions according to the successive convex approximation and interior-point methods. Extensive simulation results verify the efficiency of the proposed algorithm and demonstrate that Using UAVs used to enhance the maritime coverage.
