Performance analysis of legitimate UAV surveillance system with suspicious relay and anti-surveillance technology

Abstract

We propose a legal Unmanned Aerial Vehicle (UAV) surveillance system to perform passive surveillance or active jamming while in the presence of a suspicious relay or source, where a UAV works in half-duplex mode and the relay/source deploys artificial noise to prevent monitoring. Three schemes are considered for a Multiple-Input Multiple-Output (MIMO) UAV: surveilling followed by jamming; jamming followed by surveilling; and two-stage surveilling. For each scheme, a closed-form expression of surveilling non-outage probability is derived, and surveilling performance under different system configurations is analyzed. Monte Carlo (MC) simulation validates derivation correctness.
