Abstract :
A practical failure compensation technique for active phased arrays is presented. It is suitable for real-time applications and is applicable to any distribution of the failures across the array. It is independent of the external signal environment and is capable of achieving substantial performance improvement across broad selectable angular sectors at the expense of some additional performance degradation in other less important sectors
