This paper provides a review of the Teager–Kaiser (TK) energy operator and its extensions
for signals and images processing. This class of operators possesses simplicity and good …

Several papers have been published recently on the quasi-maximum likelihood (QML)
approach for the polynomial phase signals (PPS) parameter estimation. The QML is …

This article addresses the problem of fast and accurate chirp signal parameter estimation in
fractional Fourier domains. By employing a perturbation analysis, it is shown that the …

In this paper, we consider a three-dimensional parameter space, which is the time-frequency-
chirprate (TFCR), to characterize the time-varying features of multi-component non …

A new approach to the estimation and classification of nonlinear frequency modulated
(NLFM) signals is presented in the paper. These problems are crucial in electronic …

Effective quasi maximum likelihood-random samples consensus algorithm is proposed for
the instantaneous frequency (IF) estimation of overlap** signals in the time-frequency (TF) …

In this article, an efficient method for parameter estimation of polynomial phase signal (PPS)
is proposed. Instead of the existing methods based on parametric ergodic search or phase …

In this paper, we consider a three-dimensional parameter space, which is the time-frequency-
chirprate (TFCR), to characterize the time-varying features of multi-component non …

The index of the peak magnitude of the fractional Fourier transform (FrFT) of linear frequency
modulated (LFM) signals has been widely used as a powerful chirp-rate estimator. In this …

Bistatic synthetic aperture radar (BiSAR) has been attracting worldwide attention because of
its forward-looking imaging and high anti-interference. In harsh environment, it is vital for …
