Abstract
A device which can accurately detect even objects in very close proximity to a vehicle and at the same time can reliably detect more distant objects has means (MM) that can execute a selection of those reception pulses (EI) whose chronological offset in comparison to the respective transmission pulses (SI) emitted is of such a magnitude that these reception signals (EI) result exclusively from reflections against objects from a selected distance range correlating to the chronological offset. Means (DG) are also provided that permit the transmission pulse power to be increased and decreased as the distance range rises and falls.

A device for detecting objects in the vicinity of a vehicle by means of pulse radar, which has a transmitter that emits transmission pulses, and a receiver that evaluates reception pulses reflected against objects, characterized in that means (MM) are provided, which can execute a selection of those reception pulses (EI) whose chronological offset in comparison to the respective transmission pulses (SI) is of such a magnitude that these reception signals (EI) result exclusively from reflections against objects from a selected distance range correlating to the chronological offset and that additional means (DG) are provided, which permit the transmission pulse power to be increased and decreased as the distance range rises and falls.
