Abstract :
We tackle the problem of applying to echographic imaging those frequency domain synthetic aperture focusing techniques (SAFT) commonly used in the field of synthetic aperture radars (SAR). The aim of this research is to improve echographic image resolution by using chirp transmit signals, and by performing pulse compression in both dimensions (depth and lateral).
