METHOD FOR RADIOLOCATING MEASUREMENT OF VESSEL HULL VIBRATION AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC G01H9/00 G01S13/08 

FIELD: physics, measurement.

SUBSTANCE: group of inventions is related to the field of controlling and measuring equipment, namely to methods of surface sea vessel or aircraft body vibration measurement, and also measurement of any radiolocating object vibration with the help of coherent-impulse radiolocating distance finder. Method for radiolocating measurement of vessel hull vibration and device for its realisation. At first hydrometeorological and noise characteristics are considered and specified in the region of vessel hull vibration measurement. Afterwards vibrating object is probed by radio pulses of SHF-range, and reflected signals are received, being phase-modulated by frequency of vessel hull vibration, with further determination of local and integral characteristics of vibration realised with the help of multiway fixing switch, which forms fixed value of strobe signal delay. Device is additionally suggested for method realisation. Availability of multiway fixing switch in device makes it possible to change controlled area of vibrating surface, to increase extent of radiolocating perceptibility, to increase accuracy of extended object vibration characteristics measurement.

EFFECT: provision of measurement of controlled area of vibrating surface, increased extent of radiolocating perceptibility, increased accuracy of extended object vibration characteristics.
