Description

Time-space-frequency analysis of electromagnetic pulses (EMP) generated by a kJ-laser interaction is presented. The correlation between signals received by several loop antennas is investigated to determine spatial variations in the local electromagnetic field within and around the interaction chamber. A fast Fourier transform of antenna signals is performed to resolve the temporal and frequency components ranging from the megahertz to gigahertz.
