#CMT# #/CMT# The method involves decomposing a stationary signal (37) i.e. synthetic aperture radar video signal, into M sub-signals (311) such that the sub-signals have different spectrums (314) and concatenation of the spectrums reconstitutes a signal spectrum. An analytic identification model is defined to identify M sequences of samples corresponding to the sub-signals and to extrapolate the sequences. Spectral decomposition of sub-signals (313) corresponding to the extrapolated sequences is performed. Concatenation of the spectrums obtained from the decomposition of the signal (37) is performed. #CMT#USE : #/CMT# Method for extrapolating a stationary signal i.e. synthetic aperture radar video signal, having a pore zone, by multi-channel spectral decomposition of the signal, for remote or Doppler high resolution analysis of the signal. #CMT#ADVANTAGE : #/CMT# The method permits to improve spectral resolution of the processed signal with sufficient bandwidth for improving quality of an image, and to resaturate temporal or frequential continuity of representation of the stationary signal. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation illustrating a method of extrapolating a stationary signal.'(Drawing includes non-English language text)' 37 : Processed stationary signal 38 : Temporal signal 39 : Unique signal 311, 312, 313 : Sub-signals 314 : Spectrums. |
