  • FMCW DISTANCE MEASURING METHOD AND DEVICES
    Publication number: 20120283987
    Abstract: A method of measuring the distance uses a terminal A and a terminal B, each terminal comprising an FMCW generator for generating a signal having a predetermined frequency to time function. Terminal A transmits a transmit signal in transmit periods, which alternate with mute periods without transmission. Terminal B shifts the received signal in time from a transmit period to a mute period, for example by generating a local periodic FMCW signal, determining an adaptation of the timing of that local periodic FMCW that is needed to bring it into a predetermined timing relation to the received signal and applying the adaptation in the mute period. Terminal B transmits the shifted signal, which is received by the receiver of terminal A.
