Abstract : This report describes a serial phase shift beamformer characterized by a charge transfer device for progressive clocked transfer of quadrature component analog samples of the scanned outputs of a multiplicity of transducer elements in a curved array. Weighting resistors effect scaling of the analog samples during parallel readout of X and Y component samples prior to summation of like components and derivation of the square root of the sum of the squares of the X and Y summations to provide formed beam amplitude signals.
