The method and system for reducing phase error of phased array radar beam steering controllers having digitally controlled phase shifters includes the monitoring (34a-34e) of individual digitally controlled phase changer elements (46a-46e), determining (38) an additive phase correction to reduce the number of failed phase changer elements (46a-46e), determining (40) whether said additive phase correction is achievable by comparing the stuck bit state at each said failed changer elements (46a-46e) with said additive phase correction, and adjusting (42, 44) the phase commands to the nearest values which can be achieved if the additive phase correction is unachievable. |
