Abstract :
Experimental results obtained with a self-calibrating 32-element DBF (digital beamforming) array are presented. Results are shown for a variety of beamforming operations, such as the low sidelobe pattern and the adaptive nulling pattern. The effects of errors due to mutual coupling, quantization, intermodulation, multipath, and calibration mismatches were considered.<>
