An experimental investigation of the rhombic EMP simulator under pulse excitation

The voltage pulse at the driving point of the simulator and the associated current pulses that travel along the conducting tubes that form the rhombus are measured with different loads. The complex sequence of electromagnetic pulses (including the incident pulse, the reflected pulses from the load, and other reflection points) is measured on the metal ground plane. The origin (localization) of each pulse is carried out. On the basis of the Fourier transformation of the waveforms in the time domain, the spectrum of the electromagnetic pulse in the frequency domain is obtained. The characteristics of the simulator with the two types of excitation (continuous wave and pulse) are shown to be consistent.
