Abstract
Design trade-offs in a programmable time-delay-and-sum digital beamformer built by MPL will be discussed. This dynamic beam-former permits the incorporation of slow changes in element positions and/or beam steering direction while the beamformer carries out the real-time formation of 1300 beams from 32 input sensors. The sensors are distributed in a random but known manner over an aperture diameter of up to 800 λ (at 400 Hz).
