Abstract:
1. A radar antenna array comprising: two different antenna arrangements, a first one of the antenna arrangements having a first group of patch exciters for transmitting and a second one of the antenna arrangements having a second group of patch exciters for receiving, the two antenna arrangements being configured to generate, via the first group of patch exciters and the second group of patch exciters, antenna power emissions having dominant secondary lobes which are mutually offset so as to have the effect that if the first one of the antennas is transmitting and emits power in its secondary lobe towards a target, the second one of the antennas that is receiving has its minimum lobe if the first one of the antennas is transmitting and emits power in its secondary lobe towards the target and the second one of the antennas receives substantially no power from the direction of the target, so that the first one of the antennas that is transmitting and the second one of the antennas that is receiving point in the direction of the target in view of their antenna characteristics.
