Detection of high power microwaves

The growing threat to critical infrastructure by high power microwaves (HPM) also increases the importance of detection facilities for electromagnetic fields with high field strength. We discuss HPM detection principles as well as capabilities and limitations of existing HPM detectors. Then we describe the basic requirements for a system for the detection and identification of HPM threat signals and a demonstrator of a single-channel HPM detection system for mobile and stationary use. The system allows the measurement of amplitudes within a very high dynamic range, the pulse width, pulse repetition frequency and the number of pulses.
