Abstract
A method and system/circuit for multi-beamforming signal processing are provided. The circuit includes a plurality of basic modules associated with a plurality of transducers. Each basic module includes a first and second processing stages operative for introducing time delays of higher and lower temporal resolutions to the signals processed thereby respectively, and a path selector multiplexer module managing the signal coupling between the first and second stages. The first processing stage is connectable to one of the transducers via a first port and includes a network of first type time delay channels defining L signal paths operative at a relatively high sampling rate and adapted for providing L respectively different time delays of high temporal resolution. The second processing stage includes an array of N second type time delay channels operable for shifting signals processed thereby by any number up-to K samples of a lower sampling rate.
