Abstract (en)
An antenna system has a number of transmission antennas (10) arranged at respective positions at corners of a polygon. A plurality of groups (14a-f) of reception antennas (12) are provided, each at positions between the positions of transmission antennas at neighbouring corners of the polygon. A target reflects the signals from the transmission antennas (10). Reflections of the signals of each of the are received in the reception antennas (12). An antenna output signal is computed from a complex weighted sum of reflections corresponding to different combinations of transmission antennas and reception antennas.
