Abstract

Limited diffraction beams such as Bessel beams and X waves obtain good resolution over very large depth of field but, they have high sidelobes. We have developed a summation-subtraction method for decreasing the sidelobes. The method requires three transmits, decreasing the frame rate to one third. Although others have tried the same technique, we apply it to limited diffraction beams and obtain an analytic description.
