WAVE DETECTOR OF NON-UNIFORMITY Russian patent published in 2007 - IPC G01V3/12 

FIELD: the wave detector of non-uniformity refers to systems of non-destructive control and may be used in different radio technique arrangements including systems of radiolocation and of ultrasound diagnostics.

SUBSTANCE: the increase of noise immunity at detection is made due to using resonance properties at broadband sounding and in-phased excitation of oscillatory process in non-uniformity. The wave detector of non-uniformity has a generator of a broadband signal (1), a generator of radio impulse succession (2), a radio impulse synthesizer (3), a oscillators block (4). The synthesizer (3) and the oscillators block (4) form a multi-channel sounding system having a lines delay block (5-1,..., 5-n), a transmitting radiators block (6-1,...,6-n).The receiving part of the detector has a receiving radiator with an amplifier-limiter (7), an adaptive robust filter (8), an amplitude detector (9), a control block (10), a deciding arrangement (11).The forming of the summary reflected signal is carried out directly on non-uniformity.

EFFECT: increases noise immunity at detection.
