1. A process for measuring the relative distance and speed of an object in relation to a periodically frequency-modulated continuous wave radar, which comprises:

  • extracting distance and 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; and

    calculating distance and speed of an object at each half-period from beat frequencies of two immediately preceding alternations.
