Multi-static sensor arrangement for object distance measurement, e.g. for vehicle parking, has pulse generators receiving clock signals via common data bus to produce deterministic HF oscillator signal phase relationship

摘要

The arrangement has a transmission unit (Tn) and a reception unit (Rm), each with a high frequency oscillator (HFO-Tn,HFO-Rm) and a pulse generator (PG-Tn,PG-Rm). The pulse generators are supplied with clock signals (TS,RS) from signal generators transmitted via a common data bus (B) to the transmission and reception units to produce a deterministic phase relationship between the signals from the high frequency oscillators. An Independent claim is also included for a method of operating an inventive arrangement.
