摘要： A method and a system/circuit for multi-beamforming signal processing are provided. The circuit includes a plurality of basic modules associated with a plurality of transducers (e.g. antenna elements). Each basic module includes first processing stage having a first port operative at a first sampling rates (e.g. for providing signal to/from a respective transducer), a second processing stage having N second ports operative at a second sampling rate (e.g. through which beam-components of the signal are provided thereto/therefrom), and path selector multiplexer module for managing signal coupling between the first and second stages. The first sampling rate is higher than the second sampling rate, and correspondingly the first and second processing stages are configured for introducing to the signals processed thereby time delays of higher and lower temporal resolutions respectively. The first processing stage includes a network of first type time delay channels defining L signal paths providing L respectively different time delays of the higher temporal resolution higher. The second processing stage includes an array of N second type time delay channels connected respectively to the N second ports, each o being operable for shifting a signal communicated therethrough by any number up-to K samples of the second sampling rate. The path selector multiplexer module selectively links any one of the L signal paths of the first stage with any one or more of the N second type time delay channels of the second stage.
