Method and system for reducing phase error in a phased array radar beam steering controller.

摘要

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.
