Abstract
A method includes receiving from multiple transducers (28) respective signals including reflections of a transmitted coded signal from a target. An image (42) of the target is produced by computing transducer-specific frequency-domain coefficients for each of the received signals, deriving, from the transducer-specific frequency-domain coefficients, beamforming frequency-domain coefficients of a beamformed signal in which (i) the reflections are applied pulse compression, and (it) the reflections received from a selected direction relative to the transducers are emphasized, and reconstructing the image of the target at the selected direction based on the beamforming frequency-domain coefficients.
