FIELD: physics. ^ SUBSTANCE: proposed device comprises signal source to output signal with multiple frequency components in one definite bandwidth, transmission module to transmit signal in the form of wave oscillation, module to detect mixed wave Vc resulted from mixing transmitted travelling wave VT and reflected wave VRk consisting of travelling wave VT reflected from measurement object, module to analyse frequency component of detected mixed wave Vc, and module of distance computation designed to obtain distance spectrum, process analysed data and compute distance to measurement object. ^ EFFECT: simple design, possibility to measure short distances and reduced errors. ^ 22 cl, 24 dwg |
