In this paper, we propose a legitimate surveillance system, where a full-duplex unmanned aerial vehicle (UAV) legitimate monitor with simultaneous passive surveilling and active jamming is deployed to monitor a suspicious communication link between a dubious pair on the ground. Two different scenarios for the UAV, single-input single-output (SISO) and multiple-input multiple-output (MIMO), are studied. Three low-complexity linear beamforming schemes, transmit zero-forcing (TZF)/maximum ratio combing (MRC), maximum ratio transmission (MRT)/receive zero-forcing (RZF), and maximum ratio transmission (MRT)/maximum ratio combing (MRC) are considered for MIMO UAV. The surveilling non-outage probability is derived and analyzed, and optimal jamming power is obtained. Simulation and numerical results are used to validate the derivation.
