Research on multi-mode drone jamming technology

With the explosive growth of low-altitude UAV applications, the security threats they pose have prompted countermeasure technology research to become a hotspot. In this paper, a multi-mode jamming scheme based on software radio is proposed for UAV communication and navigation links. The UAV data link is blocked by comb and sweep interference techniques. Combined with generative navigation spoofing technology to achieve navigation link deception, the interference parameters are optimized by introducing the third-generation genetic algorithm to improve the success rate of interference. Based on the software radio, the UAV is tested for jamming, and the experiment shows that: comb jamming and frequency sweeping jamming can cut off the control link, and the navigation deception makes the UAV deviate from the preset path, which realizes the effective jamming of the UAV.
