In this work we present a new synthetic aperture technique, derived from the conventional SAFT, where only one element in emission and two in reception are used (2R-SAFT). This new technique suppresses the grating lobes of the conventional SAFT and allows obtaining images with a better contrast and signal-noise ratio, at the same time that minimizes the hardware requirements of the imaging systems and maintains a high frame rate.
