1. An electromagnetic event detection system comprising:

  • an electromagnetically shielded enclosure; and

    a detector configured to detect an electromagnetic field event, the detector comprising;

    an antenna;

    a circuit electrically connected to the antenna, the circuit including;

    an equalizer communicatively connected to the antenna via a direct current isolation circuit, the equalizer compensating for differentiating frequency response of the antenna;

    a logarithmic amplifier electrically connected to the equalizer and configured to generate a range of signals based on signals received at the antenna; and

    a peak detector receiving signals from the logarithmic amplifier and configured to capture a peak value of the signals;

    wherein an electromagnetic field event is detected at least in part based on the peak value.
