A new electromagnetic jamming system for unmanned aerial vehicles

摘要

In this paper, a new electromagnetic jamming system (EJS) is presented to interfere with the signals of unmanned aerial vehicles (UAVs). In particular, the remote control and global positioning system (GPS) signals required for UAV flight are jammed by the EJS which leads to a loss of UAV control. A saw tooth wave is employed and the bandwidth and center frequency can be adjusted to satisfy different requirements. To evaluate the performance of the system, several experiments were conducted in an outdoor environment. The results obtained show that the system is robust and practical.
