Pulsed radar having a reception circuit divided into two channels with measuring regions having different scanning speeds

摘要

A device 100 is disclosed for detecting and/or evaluating at least one target object such as objects in the surrounding field of a motor vehicle wherein a sensing region or detection gate is displaced over a measuring region at a scanning speed in such a way that a target specific speed measurement during continuous detection is ensured with a short latency time. The disclosed arrangement 100 comprises a reception circuit 70 divided into at least two channels 72,74 which can be operated independently of each other. The first channel 72 of the reception circuit 70 is arranged to displace the sensing region or the detection gate over the whole measuring region at a constant scanning speed and the second channel 74 of the reception circuit 70 is arranged to displace the sensing region or the detection gate over the measuring region at a variable scanning speed and/or for a preset period of time at a diminishing scanning speed at a preset position inside the monitoring region.
