Coupling-based wideband digital phased array calibration techniques
Recently, interest in phased array radars for diverse applications has been rising because of their versatility and recent efforts to reduce their cost. All phased array radars require some form of calibration to periodically ...
TECHNIQUES AND INSTRUMENTATION FOR PHASED ARRAY CALIBRATION
(2020-05-08)
Active phased arrays suffer the inherent problem of excitation errors, i.e., incorrect phase and amplitude excitation of the antenna elements. Excitation errors degrade critical performance parameters since they increase ...
