Analysis of the Peak Voltage of Parabolic Antenna Coupled Output under UWB-HPM Pulse Irradiation

Abstract:
This paper analyzes and simulates the radar output peak voltage under the irradiation of ultra-wideband high-power microwave pulses with different center frequencies. The results show that when the narrowband radar receives highpower microwave radiation, due to the filtering characteristics of the radar antenna and the uneven distribution of the spectral energy of the bipolar Gaussian pulse, the radar output voltage is related to the radar bandwidth, the total power of the irradiated signal and the relative position of the radar and the center frequency of the irradiated signal, part of the energy does not enter the radar receiver, resulting in a decrease in the radar output peak voltage.
