Coupling Effect of High Intensity Electromagnetic Pulse on the Shipboard Integrated RF System

As electromagnetic pulse (EMP) weapons are widely used in modern maritime operations, the electronic equipment of shipboard integrated radio frequency (RF) systems are vulnerable. In order to analyse electromagnetic interference, this paper introduces the waveform and parameter characteristics of high-power microwave (HPM), ultra-wideband (UWB) electromagnetic pulse, and high-altitude nuclear explosion electromagnetic pulse (HEMP), and studies the coupling effect of typical strong electromagnetic pulse on the electronic equipment of the shipboard integrated RF system. By changing the incident direction, polarization direction, and amplitude of the electromagnetic pulse, the coupling law of the strong electromagnetic pulse to the phased array equipment, electronic reconnaissance equipment, and countermeasure equipment of the shipboard integrated RF system is summarized. For the different types of EMP waveforms, HPM is the most harmful to shipborne integrated RF system with a coupling voltage of about 50 V, while HEMP is the least harmful with a coupling voltage of about 24 V, which provides a reference for the electromagnetic protection of the future shipboard integrated RF system.
