FIELD: technology for locating immobile objects, direction finding, radio and radio-technical reconnaissance, possible use in telemetric communication systems as finder of periodic series of mutually coherent radio-impulse signals with known frequency of carrier oscillations.
SUBSTANCE: claimed device contains input device, first compensating amplifier, band filter, dispersion delay line, linear-frequency-modulated heterodyne, adder, second compensating amplifier, check connection amplifier, delay line with extended interaction, amplitude detector, threshold device, mono-stable multi-vibrator and commutator, interconnected in a certain way.
EFFECT: simplification of device with substantially increased threshold sensitivity when finding coherent radio-impulse series and substantially reduced time of detection.
