Abstract
In a method for operating a radar system, the object is to determine by simple means and at low cost the distance and/or the radial velocity of at least one target object with high resolution. For this purpose, in each measuring phase of the measurement process in the "pulse FMCW radar system", switchover between a transmission mode and a receiving mode is effected a multiple number of times and at short intervals of time. In the transmission mode, all receiving units of the radar system are switched off, while a pulse-shaped (frequency-modulated) transmission signal with time-successive transmission pulses having a specific pulse-on time and a specific carrier frequency is emitted from at least one transmitter unit of the radar system. In receiving mode, all transmitter units are switched off in the pulse-off times of the transmission pulses, while from at least one receiver unit all reflection signals originating from the last emitted transmission pulse are detected as received signal from the entire observation range before emission of the next transmission pulse. The distance and/or the radial velocity of the reflection objects is determined indirectly by the signal processing …
