Chirplet是什么
WebIn signal processing, the chirplet transform is an inner product of an input signal with a family of analysis primitives called chirplets. [2] [3] Similar to the wavelet transform , … Web8-D "chirplet space" (with appropriate smoothing kernel). Furthermore, the chirplet transform is a framework for deriving new signal represen-tations. The chirplet transform is a mapping from a 1 -D domain to an 8-D range (in contrast to the wavelet, for example, which is a 1 -D to 2-D mapping). Display of the 8-D space is at best difficult.

WebThe chirplet transform: physical considerations. Abstract: We consider a multidimensional parameter space formed by inner products of a parameterizable family of chirp functions with a signal under analysis. We propose the use of quadratic chirp functions (which we will call q-chirps for short), giving rise to a parameter space that includes ... WebABSTRACT Time-frequency analysis (TFA) has been widely used in seismic processing and interpretation. A good time-frequency representation can preferably characterize geologic spatial distribution and detect hydrocarbon reservoir anomalies. This paper applies a robust seismic TFA method based on the general linear chirplet transform (GLCT). The GLCT …
