ABSTRACT:
A process for measuring the relative distance and speed of an object in relation to a periodically frequency-modulated continuous wave radar includes extracting the distance and the speed by combining beat frequencies derived from a mixture of emitted and reflected signals being respectively obtained during ascending and descending alternations of a modulation. The distance and the speed of an object at each half-period are calculated from beat frequencies of two immediately preceding alternations.
