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.

摘要： Beamforming techniques, and corresponding implementations, are disclosed, wherein digital data adapted by a beamforming process for transmission by a plurality of transmit channels of a ESA system is manipulated by a respective plurality of delta- sigma modulation processes for causing different modifications of at least a portion of the adapted digital data in each of the plurality of transmit channels. This way, variance can be introduced between signals transmitted by the transmit channels. The manipulated data of each transmit channel can be then converted into a corresponding analog domain signal for transmission thereof via the respective antenna element. The different modification obtained by manipulating the adapted digital data by the delta- sigma modulation processes can be configured to cause a reduction in the average correlation between the quantization noise signals transmitted from the respective antenna elements after the conversion into the analog domain, so that out of band quantization noise and errors can be substantially reduced at a receiver of the transmitted signals.

摘要： A beamforming circuit for receiving and/or transmitting one or more (typically a plurality of) beams. The beamforming circuit includes: an antenna I/O module having antenna ports; a data bus connection for connecting to a data bus for communication of data streams of one or more beams to be produced (received or transmitted); a beamforming module including a plurality of beamforming channels connectable in between the data bus connection and the antenna ports for processing signals communicated between them to introduce controllable shifts (e.g. time-delays and/or phase-shifts) in order to heamform the processed signals, being received and/or transmitted. Whereby the beamforming circuit includes a cascade I/O module enabling to connect one or more additional beamforming circuits to the beamforming circuit, in a "vertical" cascade, to thereby enable forming of one or more additional beams by the beamforming modules of the one or more additional beamforming circuits. The cascade I/O module includes a plurality of cascade ports respectively connected to the plurality of antenna ports via a plurality of corresponding bypass channels. Each antenna port is connectable, in parallel, to at least one respective bypass channel and to one or more of the beamforming channels of the beamforming circuit, via a signal splitter/combiner. In transmission configuration/mode, the signal splitter/combiner is operable for combining signals from the bypass channel and the one or more beamforming channels, which are associated with the respective antenna port; and in reception configuration/mode, the signal splitter/combiner is configured and operable for splitting the signals of the respective antenna port to form duplicates thereof at the respective bypass channel and the one or more beamforming channels associated with the respective antenna port.
