Abstract
A beamformer control system includes a primary control and secondary controls so that delay and apodization beamformation profiles can be generated on a dynamic and distributed basis with sparsely sampled base delay and apodization data sets first expanded to the final values by the primary control and then further expanded in the secondary controls associated with multi-processing channels of the beamformer systems. The beamformer control system coordinates the transmit and receive beamformer systems preferably using data sets common to all beamformer systems, and by advantageously specifying to all beamformer systems, processing mode trade-offs among the signal nominal center frequency, the range spatial resolution, and the number of beams. The beamformer control system supports multiple simultaneous beam operation, as well as beam-to-beam adjustable frequency and synthetic aperture operations. Further, the present beamformer control system maintains beam-to-beam coherent receive beamformation and supports adaptive beamformation.
