Design and Implementation of Communication Jamming System for Small UAV Based on FPGA
Abstract：To deal with the problems such as unauthorized UAV and UAV disturbing people due to the rapid development of UAV， according to the technical principle of direct digital frequency synthesis， proposes a UAV jamming system based on communication jamming. Field programmable gatee array is selected as the core chip to design a dual sideband jamming emitting hardware structure without image suppression algorithms and filters. And the feasibility and effectiveness of the proposed system is verified by relevant tests.
Keywords：direct digital frequency synthesis；UAV；communication jamming；system design； FPGA
