Abstract:
An apparatus for detecting low level pulses of millimeter wave electromagnetic radiation has an electromagnetic field receiver including: a receiving antenna configured to receive an input signal at one or more frequencies ranging from 10 GHz to 100 GHz, and a diode detector coupled to the receiving antenna, the diode detector providing an output voltage signal in response to the input signal. The apparatus also has an electronic signal processor. This produces an amplified voltage signal. The electronic signal processor also produces from the amplified voltage signal a reduced bandwidth, unipolar voltage signal proportional to a peak power of the input signal. The electronic signal processor uses this to produce an amplified reduced bandwidth, unipolar voltage signal. At least the electronic signal processor is encased in an electronically shielded housing.
