A receiving array with several antenna columns is provided to determine the target angle of deviation in a pulse radar system. There is one downlink mixer (43) for each antenna column and a delay line (9) between at least one antenna column and the downlink mixer. An evaluation unit (6) determines the phase difference between the output signals of the downlink mixers corresponding to the Doppler shift of a radar target. From this the angular position of the target can be determined. The received signal may be scanned in order to determine the Doppler shift and hence the speed of the target.
