Method for depth compensation of amplitudes of echo-signals in an ultrasonic measuring device which uses the pulse-echo-technique

摘要

A method and apparatus for depth compensating the amplitudes of echo signals in an ultrasonic measuring device to compensate for virtually unlimited depth measurements using an amplifier adjustment curve supplied in real time which is triggered with every radiated pulse, and using the time-synchronous clock steps of a clock pulse generator converted to an analogue output signal through a D/A-converter.
