This paper describes an acousto-optic (AO) receiver for frequency sorting and direction finding (DF) measurement. A novel concept of the cueing system is described that provides high resolution signal analysis covering a wide instantaneous bandwidth. Two critical components for the cued DF receiver are AO Bragg cells and Bulk Acoustic Wave (BAW) delay lines. Recent experimental results of these two devices are reported.
