WebMar 31, 2024 · Different from the transform kernels in CT and PCT, i.e., chirplet kernel and polynomial kernel, a new transform kernel p * (t) is adopted in the proposed KRR-CT. In view of this new transform kernel, the proposed KRR-CT has more powerful capability in the analysis of noisy signal with highly nonlinear IF than previous CT and PCT. WebPolynomial chirplet transform (PCT) can effectively characterize the instantaneous frequency (IF) of mono-mode frequency-modulated (FM) signal, but it is unsuitable to analyze multimode signals. Here, we propose synchrosqueezing PCT (SPCT) for amplitude-modulated (AM) and FM signals with multimode, and apply it to tight sandstone gas …
