A unique ultra wide band receiver is provided that blends together RF and photonic technologies. The receiver has application as a steering mechanism ( 600 ) for a much higher resolution receiver. Some implementations can provide at least four times shorter scanning and processing time than current technology using Bragg-cell technology as a direct replacement for state of the art A/D technology at a high IF frequency conversion rate. The dynamic range offered through use of Bragg-cell processor technology, as used in this IF application, provides greater bandwidth than comparable A/D technology.
