Abstract :
Surface acoustic wave (SAW) filters have been developed to code the information received by an antenna array and sum them into a single signal. In post-processing, these waveforms are retrieved exploiting the orthogonal propagation in each SAW filter. Thus, a proof a concept of beamforming and imaging using SAW filters is presented.
