A method for coherently acquiring backscatter and angular scatter information was described using a synthetic aperture based approach on a 1D linear array. The method of angular scatter imaging uses a single element synthetic aperture approach to acquire reflected acoustic data at multiple scattering angles. The SAAS imaging approach using the translating apertures algorithm (TAA) half element step samples K-space in between the backscatter and full element TAA K-space samples. It was found that by using a K-space motivated algorithm, lateral spatial frequency sampling was increased on an otherwise undersampled linear array. The results show that the beamplots for the backscattered case, the grating lobes rise to a level around -23 dB.
