A continuous-wave radar set is disclosed which is additionally usable as a transmitter for transmitting messages, e.g., voice, data, or control information. Besides a first modulator (SM) which produces a sawtooth or triangular frequency modulation of the radar RF signal, there is an additional modulator (ZM) which modulates the radar RF signal with a useful signal during the flyback, i.e., in a phase in which the signal is not used for radar purposes. To achieve exact synchronization between the two modulators, both modulators are controlled by the same clock generator (T).
