Abstract：Addressing the bottleneck of uncrewed aerial vehicles (UAVs) in complex electromagnetic environments, this paper systematically analyzed the classification and action mechanisms of electromagnetic interference (EMI) sources, EMI coupling paths, and nonlinear responses within UAVs. A multi-scale interference theoretical framework to address UAV anti-EMI issues was proposed for constructing. Five key anti-interference technologies were investigated: algorithm-level anti-interference, electromagnetic shielding, dynamic filtering, system-level collaborative protection, and optical fiber transmission technology. Respectively, algorithm-level anti-interference focused on integrating lightweight models with edge computing; electromagnetic shielding aimed to break through the low-frequency efficiency bottleneck; dynamic filtering explored the fusion of neural networks and bionic mechanisms; system-level collaboration established a closed-loop system of “interference identification-dynamic suppression-system reconstruction”; and optical fiber technology realized physical-layer signal isolation. This research offers theoretical and technical solutions for UAV engineering applications in environments with substantial electromagnetic interference, and is of significant importance for enhancing the electromagnetic compatibility of UAVs.
