Chirp excitation [PDF]

Journal of Magnetic Resonance, 2017
The paper describes the design of broadband chirp excitation pulses in NMR. We first develop a three stage model for understanding chirp excitation in NMR. We then show how a chirp $π$ pulse can be used to refocus the phase of the chirp excitation pulse. The resulting magnetization still has some phase dispersion in it. We show how a combination of two

Chirp, Self-Chirp and Meta-Chirp in Sampled Fibre Gratings

Photosensitivity and Quadratic Nonlinearity in Glass Waveguides: Fundamentals and Applications, 1995
Sampled Bragg gratings consist of a periodic modulation of the amplitude and/or the phase of the Bragg grating. In the frequency domain, their reflectivity spectrum shows a number of equally spaced peaks, covering a range of wavelengths determined by the Fourier contents of the modulation, or "sampling" function.

Compressive Chirp Transform for Estimation of Chirp Parameters

2019 27th European Signal Processing Conference (EUSIPCO), 2019
This paper develops a new algorithm for estimating the parameters of multiple chirp signals in noise. The proposed method uses Compressive Sensing (CS) formulation of the Discrete Chirp Fourier Transform (DCFT) basis to achieve superior estimator performance.
