Abstract :
The partitioned modified chirp Z-transform (PAM-CZT) is a signal processing technique which aids in the analysis of acoustically propagated ocean noises. The technique utilizes the fast Fourier transform (FFT) to allow real time computation in which long time data are processed in short-time-ordered sequences, thus providing spectral analysis to any frequency resolution.
