Abstract
An apparatus for electrically blending echoes from a plurality of focused beams into a composite image having reduced image artifacts. The apparatus comprises a transducer generating a sequence of beams having different focal points and converting resultant echoes into electrical signals, a receiver with its gain adjusted according to (1) time and (2) the transmitted beam, a multiplier that develops the product of the receiver output and a gain selected both by the transmitted beam and (time), and a summing network that adds together outputs of the multiplier that originated from the same sound scatterer.
