Abstract :
In this paper, a modification to the delays used in reception beamforming is introduced that allows one to sharply reduce the echoes centered at the fundamental frequency and to keep the echoes centered at the second harmonic, while preserving the focusing performances. Such a modification can be easily implemented in echographic equipments.
