Fast discrete chirp Fourier transforms for radar signal detection systems using cluster computer implementations

A useful processing tool for time-frequency signals known as the discrete chirp Fourier transform (DCFT) and its implementation using cluster computers for application to radar signal analysis. a time-frequency signal is defined as a signal whose spectral distribution changes with time. chirp signals, as time-frequency signals which are linearly frequency modulated, are widely used in many detection, estimation, and imaging radar applications. DCFT implementations for radar systems provide important information about the nature of radar signals and allow to determine certain spectral characteristics used in signal detection and estimation processes.
