Abstract
Abstract The device measures the distance "h" separating it from an object. It consists of a transmitter (9, 7, 5) sending a frequency-modulated wave towards the object and a receiver (15, 17) for receiving the wave after reflection by the object. A mixer (20) provides a beat frequency wave produced between the transmitted and received waves. A high-speed digital processor (30) carries out a time-frequency transformation on the beat frequency wave. A control circuit (50) provides the user with the value of "h" by acting mainly on the transmitter and the high-speed digital processor. <??>Application to radionavigation. <IMAGE>
