ABOUT DETERMINATION OF A DISTANCE UP TO THE OBJECT AT THE RATIONAL CHOICE OF THE FORM OF THE ACOUSTIC SIGNAL

Effect of the form of the acoustic pulse radiated by the piezoceramic transducer, on precision of determination of a distance up to the object is probed. The expediency of application of acoustic pulses by duration three and five half-cycles on a resonant frequency of a transducer is established. Forms of the relevant pulses of exciting electric voltage are given. Estimations of a measuring error of a distance up to the object are realized.
