The requirements for wide-band multifunction phased arrays are outlined; although canonical phased arrays are ideally suited for narrow band operation and have graceful degradation of performance when some of their elements fail, other array configurations are shown to be more suitable for phased arrays required to operate over wide bands. Novel controlled redundancy arrays are shown to meet all the requirements of wide-band multifunction phased arrays.
