Phased array antenna and method for processing received signals in a phased array antenna

摘要

The received signals processing method involves assigning, once or permanently, one individual phase value, which is normally distributed from a phase range within a decorrelation unit (8), to each receiving element (E-1 to E-N) of a phased-array antenna. The normally distributed phase values are added up to oscillator signals (LO-1 to LO-N). The phase displacement corresponding to a receiving direction of the antenna is deployed on complex baseband-signals (IQ-1 to IQ-N) within another decorrelation unit (9) in each receiving path. An independent claim is included for a phased-array antenna.
