Design of Portable Jammer for UAV Based on SDR

Unregistered flight of unmanned aerial vehicle (UAV) poses a new challenge to the security of low altitude airspace. This paper proposes an interference scheme for UAV based on software defined radio(SDR), which provides a means for UAV supervision and enforcement. In this scheme, the generated GPS interference is firstly used to provide virtual location information for UAV, and then sweep-frequency jamming is used for suppressing UAV's communication signal. The feasibility of the design is proved by experiments.
