Title:
An electromagnetic field detection system and a method for the same
Document Type and Number:
Japanese Patent JP6053520
Kind Code:
B2
Abstract:
Detectors and other apparatus for determining the presence of electromagnetic events are disclosed. One such system includes an electromagnetically shielded enclosure and a detector configured to detect an electromagnetic field event occurring in the proximity of the enclosure. The detector includes an antenna and a circuit electrically connected to the antenna. The circuit includes electronics communicatively connected to the antenna via a direct current isolation circuit, and an equalizer compensating for the differentiating frequency response of the antenna. The circuit also includes 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. An electromagnetic field event is detected at least in part based on the peak signal value.
