Abstract: The present disclosure relates to a concept for detecting radar targets. A plurality of first receive signals is received from first antennas of an antenna array. A first combined range-Doppler map is determined by combining range-Doppler maps of each of the first antennas. First confirmable range-Doppler cells of the first combined range-Doppler map are determined which match a predetermined confirmation criterion. A plurality of second receive signals is received from second antennas of the antenna array. A second combined range-Doppler map is determined by combining range-Doppler maps of each of the second antennas. Second confirmable range-Doppler cells of the second combined range-Doppler map are determined which match the predetermined confirmation criterion. The first and second confirmable range-Doppler cells are combined to obtain a set of confirmable range-Doppler cells. Values of the first and the second combined range-Doppler maps corresponding to the set of confirmable range-Doppler cells are summed to obtain summed values of the combined confirmable range-Doppler cells. Summed values of the total confirmable range-Doppler cells exceeding a predefined selection threshold are selected for target detection.
