This paper investigates joint position and power control for downlink covert communication in a dual-UAV system, which consists of a UAV transmitter, a terrestrial receiver, a passive warden, and a cooperative UAV jammer. First, based on classical probability theory, the optimal detection threshold and the minimum detection error probability of Willie are analytically derived under the considered dual-UAV covert communication model. Then, by incorporating UAV mobility and controllable transmit power, closed-form expressions are obtained to characterize the optimal UAV positions and power control strategies under both transmission outage and covertness constraints. Finally, extensive numerical results are provided to validate the analytical findings and to demonstrate that the proposed joint position and power control scheme can substantially enhance the covert transmission performance of dual-UAV systems.
