Experimental Study of Radio Frequency Drone Jamming

Illegal operations of drones pose significant threats to public security and personal privacy. This research aims to develop a cost-effective drone jammer to eliminate the illegal operations of drones. Barrage jamming and sweep jamming techniques were implemented using Software-Defined radios (SDR) platform called HackRF One. The results showed that as the amplitude of the analogue barrage jamming signal increases, the strength of the signal increases, and jamming efficiency improves. Also, the results demonstrated that jamming efficiency is better at a sampling rate of 20 MHz. The performance of the digital barrage jamming using Quadrature Phase Shift Keying (QPSK) modulation and Differential Quadrature Phase Shift Keying (DQPSK) modulation was better than Binary phase Shift keying (BPSK) modulation, and 8 PhaseShift Keying (8PSK). The results of the sweep jamming technique were unsatisfactory. The recommended jammer that achieved the optimum results is based on the analogue barrage jamming technique, and the signal is fast noise with an amplitude of 15, a sampling rate of 20 MHz, and a bandwidth of 20 MHz. The recommended jammer successfully jammed the drone that was placed 1 m from the jammer and 16 m from the remote control.
