An acoustooptic-phased-array antenna beamformer with N multiple simultaneous beam generation capability is 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) + f1,..., f(C) + f(N), respectively. f1, ... f(n),..., f(N) control the carrier and phase values of the N independent beam generation signals, n being the beam number. Using f(c) = 60 MHz, and N = 2, 0-2-pi phase control is achieved using f(n) = 0-460 KHz. A dynamic range of 54.5 dB at 1 MHz and carrier-to-noise of 113.4 dB / Hz at 1 MHz is measured for a 120 MHz carrier. One-dimensional transmit / receive antenna beam scanning can be provided by this system.An acoustooptic-phased-array antenna beamformer with N multiple simultaneous beam generation capability is 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) + f1,..., f(C) + f(N), respectively. f1, ... f(n),..., f(N) control the carrier and phase values of the N independent beam generation signals, n being the beam number.
