The growing threat by high-power microwaves (HPM) also increases the importance of capabilities to detect high-strength electromagnetic fields. Fraunhofer INT has developed a demonstrator of an HPM detector with extended detection features for mobile and stationary use. It allows the measurement of high dynamic amplitudes and of width, repetition frequency, and number of HPM pulses. A four-channel system with four polarization-independent broadband antennas and four logarithmic amplifier/detector units permits additional direction finding to a detected HPM source.
