Investigating the jamming effect of HPM with different frequencies on SDR

Year: 2024

Type: article

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.
