基于FPGA的小型无人机通信干扰系统设计与实现

Design and Implementation of Communication Jamming System for Small UAV Based on FPGA

针对无人机快速发展带来的黑飞无人机、无人机扰民等问题,以直接式数字频率合成为技术原理,提出一种基于通信干扰的无人机干扰系统,选择现场可编程门阵列作为核心芯片,设计无需镜像抑制算法和滤波器的双边带发射干扰硬件结构。相关测试验证了本系统的可行性和有效性。

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.
