The invention relates to a multistatic detection device for measuring a distance to an object comprising a transmitter (Tn) and a receiver (Rm), each of which is provided with a high-frequency oscillator (HFO-Tn, HFO-Rm) and a pulse generator (PG-Tn, PG-Rm). Said pulse generators (PG-Tn, PG- Rm) can be supplied with synchronisation signals (TS, RS) emitted by signals generators, said synchronisation signals (TS, RS) being transmitted by means of a data bus (B) common for the transmitter (Tn) and the receiver (Rm). The relation of the deterministic phases of high-frequency signals can be produced by the high-frequency oscillator (HFO-Tn, HFO-Rm). The inventive operating method, in particular for the inventive detection device, consists in feeding two synchronisation signals to the transmitter and the receiver by means of the common data bus (B), the transmitter signal is transmitted towards an object, the signal passing through the receiver (Rm) and contained in the data bus (B) being mixed with a reception signal reflected by the object (O), thereby making it possible to produce a measuring evaluable signal. The calibration of the measuring signal is carried out on a remote axis by determining the origin of the synchronisation signals on the common data bus, thereby making it possible to compare the phases of clock signals by means of the data bus. |
