Beamforming is a signal processing technique that utilizes an array of sensors or emitters to create directional sensitivity or emission patterns. This methodological approach investigates the weighting and phasing of signals across array elements to spatially filter incoming or outgoing waveforms, thereby enhancing signals from desired directions and suppressing interference or unwanted emissions. Its significance lies in improving spatial selectivity, signal-to-noise ratio, and system performance across diverse applications such as radar, sonar, wireless communication, and acoustics.
