A device for measurement of thickness of walls of radomes at site of mechanical processing thereof includes a generator of harmonic vibrations of microwave range, two power dividers, circulator with receiving-emitting antenna connected to it, matching attenuator, two microwave balance mixers, two formers of short pulses and flip-flop phase detector, synchronous detector and indicator. A multi-position microwave unit with connected to it additional receiving-transmitting antennas is used as circulator, the antennas are fixed on respective movable rods placed on cramp that repeats the form of the radome. Two one-pole automated switches are used as two-pole automated switch, and additionally a microwave automatic switch is introduced, besides that a computer with generator of timing frequency (microcomputer), analog-digital conveter, low frequency filter are introduced. |
