Abstract
New orthonormal bases of improved time frequency atoms are constructed . These atoms are similar to R. Baraniuk's ''chirplets.'' These new ba ses are used to unfold frequency modulated signals in the time frequen cy plane. The selection of the ''best basis'' amounts to finding an op timal covering with Heisenberg boxes with arbitrary eccentricities and orientations. This analysis is as sharp as the one provided by the Wi gner transform. (C) 1997 Academic Press.
