The paper describes a concept of an acoustooptic phased array antenna beam-former with N multiple simultaneous beam-generation capability and wide-band antenna operation feature. The system was experimentally demonstrated using a single-channel acoustooptic device driven by a signal of frequency f(c), and an acoustooptic device with N channels driven by signals with frequencies f(c)+f(1) to f(c)+f(N). It is suggested that the concept can be extended to radar bands by using gigahertz-band acoustooptic devices.
