Abstract
Adjusting a calibrated phased array includes receiving conditions data describing conditions at a phased array. The phased array comprises antenna element sets, where an antenna element set comprises antenna elements and is associated with a calibration value. The following is performed for each antenna element set. A temperature value is established for an antenna element set according to the conditions data. A temperature-dependent correction value corresponding to the temperature value is established. A correction value is determined for the antenna element set according to the temperature-dependent correction value and the calibration value associated with the each antenna element set. At least one antenna element of the antenna element set is adjusted according to the correction value.
