Sparse time-frequency distributions of chirps from a compressed sensing perspective

Year: 2008

Type: conference-paper

Abstract: Considering that multicomponent chirp signals are sparse in the time-frequency domain, it is possible to attach to them highly localized distributions thanks to a compressed sensing approach based on very few measurements in the ambiguity plane. The principle of the technique is described, with emphasis on the choice of the measurement subset for which an optimality criterion is proposed.
