Physical-Layer Reliability of Drones and Their Counter-Measures: Full vs. Half Duplex

In this article, we study the advantages and disadvantages that full-duplex (FD) radio technology brings to remote-controlled drone counter-drone systems in comparison classical half-duplex (HD) technology. We consider especially physical-layer reliability perspective has not yet been comprehensively studied. For establishing a solid analytical background, first derive original closed-form expressions evaluate demodulation detection performance of frequency-hopped frequency-shift keyed remote control signals under external or self-inflicted interference. The developed tools are verified by simulated results then used impact operation mode on operable area drones effectiveness different scenarios, linking physical layer practical safety. Analysis scenarios shows FD compared HD can improve system detect attacks from greater distance than mode. However, two-way communication between controller significantly reduces drone’s when targeted smart system.
