Abstract: The problem of concern here is instantaneous frequency rate (IFR) estimation of multicomponent two-dimensional (2-D) chirp signals. First, the 2-D cubic phase function (CPF) is defined.
Abstract: In this paper, an integrated cubic phase function (ICPF) for parameter estimation of linear frequency-modulated (LFM) signals is introduced. The ICPF extends the standard cubic phase ...
