Classification: CPC G | IPC G

Claim 14:
15. A beamforming apparatus comprising:
a phased array comprising transducers separated by a distance L configured to receive signals of a frequency (f) with a period (T) and wherein there is a time delay of +t/4 to −t/4 between signals received by adjacent transducers;
a processor configured to translate spatial input data to angular output by:
pairing each received signal according to space and time to create a first set of paired received signals;
pairing each of the first set of paired received signals according to space, angle and time to create a second set of paired signals;
pairing each of the second set of paired signals according to space, angle and time to create a third set of paired signals;
pairing each of the third set of paired signals according to space, angle and time to create a fourth set of paired signals;
continuing hierarchically to combine angles of interest with adjacent angular beams from neighboring sub-arrays to refine angular resolution until all of the spatial input has been converted to angular information of resolution at an Abbe limit;
apodizing each set of signals;
interpolating the angular information; and
forming an image from the interpolated angular information; and
wherein, all possible beam directions are detected in parallel.
