FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio engineering and can be used in radars, communication systems and other devices that use strong pulse sequences. The device described contains scanning multifrequency antenna array (1), which consists of radiant units, isotropic in scanning plane, receiving antenna array (2), consisting of waveguide horns. Horns of the antenna are located inside of oversize waveguide (6) in angle sector of 360°, delay lines (3), phase shifters (4) and transmitting antenna array (5).
EFFECT: higher pulse power of radiated signals.
