ABSTRACT:
A beamforming system includes an array of transducers that detects echo signals in a scanned region. The array of transducers produces respective electronic signals based on receipt of echo signals. The beamforming system further includes an array of multipliers (e.g., mixers) to receive the respective electronic signals (e.g., echo signals converted to an electronic form of echo signals by the transducers) from the array of transducers. A generator device of the beamforming system generates multiple oscillator signals (e.g., square wave, sine waves, pulses, etc.) based on a relatively low frequency reference signal to simulate frequencies not capable of being precisely derived from the reference signal and continuously steer a directional beam through a scanned region.
