ABSTRACT:
A system is provided for substantially continuously monitoring an electromagnetic intensity of short pulses of electromagnetic fields (E-fields) having frequencies within a broad frequency range. The system includes at least one antenna capable of sensing one or more pulses of E-fields and converting the pulses into radio frequency (RF) signals having an energy level correlated to the intensities of the E-fields. The system additionally includes at least one equalizer that normalizes the energy levels of RF signals across the broad range of frequencies and at least one modulation device that adjusts the energy levels of the RF signals output by the equalizer. The system further includes at least one RF power sensor for periodically measuring the energy levels of the RF signals output from the modulation device. Further yet, the system includes at least one power meter that determines the peak power level of at least one peak RF signal that has the highest energy level and converts the peak power level of the peak RF signal to power units. Still further yet, the system includes a computer based device that utilizes the power units output by the peak power measurement subsystem to determine the intensity of the E-field correlated with the peak RF signal as sensed by the antenna.
