Claim 0:
1. A non-transitory computer-readable medium storing instructions executable by a processor to process data from a radar circuit having multiple antennas, the instructions comprising instructions to:
access a N×M range matrix indexed by N velocity bins and M antenna combinations to obtain a first unique X×Y range slice, of a plurality of unique X×Y range slices that form the N×M range matrix, in which X is a lesser multiple of N and Y is a lesser multiple of M;
access a M×S steering matrix indexed by the M antenna combinations and S hypothesis angles to obtain a first unique Y×Z steering vector slice, of a plurality of unique Y×Z steering vector slices that form the M×S steering matrix, in which Z is a lesser multiple of S;
combine the first unique X×Y range slice with the first unique Y×Z steering vector slice to form an intermediate slice;
iteratively:
access a next unique X×Y range slice from the N×M range matrix,
access a next unique Y×Z steering vector slice from the M×S steering matrix,
combine the next unique X×Y range slice with the next unique Y×Z steering vector slice, and add the combined next unique X×Y range slice and next Y×Z steering vector slice to the intermediate slice until a beamforming slice is formed that incorporates data for all M antenna combinations for the particular set of X velocity bins and Z hypothesis angles; and

perform at least one operation on the beamforming slice.
