Abstract

This study examines the high-power microwave (HPM) jamming effect on software-defined radio (SDR). Following theoretical analysis and formula derivation of the single-tone jamming, the HPM jamming effect is validated using an SDR platform. Jamming is relatively easily achieved when the jamming signal falls within the communication system's frequency band. For out-of-band signals, a higher jamming signal ratio is needed, with the receiving front-end device's nonlinearity causing the jamming. This study highlights the susceptibility of broadband receivers to HPM jamming, demonstrating that even out-of-band threats cannot be disregarded in wideband receiver designs for strong signals such as HPM.

研究不同频率的 HPM 对 SDR 的干扰效果

本研究探讨了高功率微波（HPM）干扰对软件定义无线电（SDR）的影响。在对单音干扰进行理论分析和公式推导后，使用 SDR 平台对 HPM 干扰效果进行了验证。当干扰信号位于通信系统的频带内时，干扰相对容易实现。对于带外信号，则需要更高的干扰信号比，由接收前端设备的非线性引起干扰。这项研究强调了宽带接收器对 HPM 干扰的易感性，表明在针对 HPM 等强信号的宽带接收器设计中，即使是带外威胁也不能忽视。
