This paper is targeted towards a general readership in signal processing. It intends to
provide a brief tutorial exposure to the Fractional Fourier Transform, followed by a report on …

In this manuscript, we propose a class of linear integral transforms that extends the
capabilities of the Fractional Fourier Transform (FrFT), while preserving some key properties …

The fractional Fourier transform (FrFT) provides a valuable tool for the analysis of linear
chirp signals. This paper develops two short-time FrFT variants which are suited to the …

A new time-delay estimator is presented in this paper. It is evaluated based on the delay
property of the fractional Fourier transform with less computation and is suitable for chirp …

The realization of the parameter estimation of chirp signals using the fractional Fourier
transform (FRFT) is based on the assumption that the sampling duration of practical …

This paper presents a technique for the analysis and extraction of multiple linear chirps in a
time signal. These signals occur in nature and are becoming increasingly important in sonar …

We propose a new discrete fractional Fourier transform (DFrFT) scheme based on
eigentransforms of the centered DFT matrix and present its application to chirp parameter …

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 …

The basis functions for the fractional Fourier transform are chirp signals where a precise
relationship between the fractional parameter and the chirp angle can be established. The …
