Abstract

The invention relates to a radar system for sensing one or more target objects and to a reception apparatus in a radar system. One of the aspects of the invention is the use of orthogonal or quasi‑orthogonal spread codes in a radar system having an MIMO structure. In order to separate the radar signals emitted by the individual transmitter units from one another in the at least one reception unit, the radar signals emitted by the individual transmitter units are spread using a transmitter‑specific spread code. The spread codes are used to ascertain the propagation time of the radar signal that is scattered at a target object from the respective transmitter unit for each transmitter unit (and for each target object) and also to determine the absolute amplitude of the radar signal that is received in the respective reception unit from the respective transmitter unit. From the propagation time of the radar signal that is scattered at a target object from the respective transmitter unit, it is subsequently possible for the respective reception unit to ascertain the absolute distance of the target object. The absolute amplitude ascertained by each reception unit (for each target object) with the associated distance (propagation time) of the target object has an ideal resolution in the distance range.
