WebAbstract: The use of the chirped z-transform (CZT) for processing various communication signals has increased recently with the advent of charge-coupled devices (CCDs). In this … WebTransmitting chirped pulses provided more accurate size and distance information from the reflected echoes. In the early 1980s, Mourou recognized that adapting the technique to the optical regime would entail properly reconstructing the phases of much shorter wavelengths while compressing the pulse.
