We analyze the performance of a wireless communication setup consisting of a source (Alice), a legitimate receiver (Bob), and an eavesdropper (Eve). To enhance secrecy, a UAV-based jammer is employed to generate artificial noise. Two jamming configurations are considered: a single UAV jammer and a multi-UAV jammer configuration that establishes a virtual multiple-input multiple-output (MIMO) system using zero-forcing techniques. For both scenarios, we investigate the average secrecy capacity (ASC) and, based on this, evaluate the secrecy outage probability (SOP) performance. Closed-form expressions for ASC and SOP are derived for both configurations. Simulation and analytical results demonstrate that employing a UAV jammer substantially enhances jamming effectiveness compared to a scenario without jamming.
