Noun
A little chirp.
(physics) A wavelet whose frequency rises or falls at a constant rate.
Coordinate term: warblet
Another example of a generalized transform is the chirplet transform in which the CWT is also a two dimensional slice through the chirplet transform. Source: Internet
Other mathematical developments in radar signal processing include time-frequency analysis (Weyl Heisenberg or wavelet ), as well as the chirplet transform which makes use of the change of frequency of returns from moving targets ("chirp"). Source: Internet
