As the kernels of fractional Fourier Transform (FrFT) are in theform of chirp signals, this transform would be useful forprocessing and describing linear chirps. In this paper FrFT isused as an alternative for pulse compression of received echosignals in coded excitation ultrasound imaging. Using field ${\rmI}{\rm I}$ program, axial resolution of match… CONTINUE READING
