Abstract
Multiple receive beams are formed for each transmission for rapid acquisition. The receive aperture is shifted as a function of the position of each receive beam. Multiple receive beams with differently positioned apertures are formed in response to a single transmit beam. Alternatively or additionally, the apodization varies as a function of the position of the receive beam relative to the transmit beam. Multiple receive beams with different apodization profiles are formed in response to a single transmission. The apodization and/or aperture variations in different receive beams may reduce geometric distortion and/or clutter levels for receiving multiple beams in response to a single transmission.
