Abstract

Radio receiver-emitter for carrier wave modulated by a particular sub-carrier for radio distance measurement, which includes a first carrier wave generator VCO and a second carrier carrier wave VCO, the phases of the two VCOs being controlled from a received carrier wave modulated by a sub-carrier wave thanks to the two automatic control loops that respectively include the first VCO and the second VCO.
