A novel nonlinear frequency modulated chirp signal for synthetic aperture radar and sonar imaging
(Millî Savunma Üniversitesi, 2016-01-20)
In order to maintain average power levels as well as high range resolution, phasecoded signals are used in radar and sonar signal processing. One of the most commonly used phase-coded signals is the linear frequency modulated ...
A split-step Fourier scheme for the dissipative Kundu-Eckhaus equation and its rogue wave dynamics
(Işık University Press, 2021-01)
We investigate the rogue wave dynamics of the dissipative Kundu-Eckhaus equation. With this motivation, we propose a split-step Fourier scheme for its numerical solution. After testing the accuracy and stability of the ...
Rogue waves of the Kundu-Eckhaus equation in a chaotic wave field
(American Physical Society, 2016-03-01)
In this paper we study the properties of the chaotic wave fields generated in the frame of the Kundu-Eckhaus equation (KEE). Modulation instability results in a chaotic wave field which exhibits small-scale filaments with ...
Assessment and enhancement of SAR noncoherent change detection of sea-surface oil spills
(IEEE, 2018-01)
Oil spills are one of the most dangerous catastrophes that threaten the oceans. Therefore, detecting and monitoring oil spills by means of remote sensing techniques that provide large-scale assessments is of critical ...
Early detection of rogue waves by the wavelet transforms
(Elsevier, 2016-01-08)
We discuss the possible advantages of using the wavelet transform over the Fourier transform for the early detection of rogue waves. We show that the triangular wavelet spectra of the rogue waves can be detected at early ...
Rogue wave spectra of the Kundu-Eckhaus equation
(American Physical Society, 2016-06-15)
In this paper we analyze the rogue wave spectra of the Kundu-Eckhaus equation (KEE). We compare our findings with their nonlinear Schrodinger equation (NLSE) analogs and show that the spectra of the individual rogue waves ...
Compressive spectral method for the simulation of the nonlinear gravity waves
(Nature Publishing Group, 2016-02-25)
In this paper an approach for decreasing the computational effort required for the spectral simulations of the fully nonlinear ocean waves is introduced. The proposed approach utilizes the compressive sampling algorithm ...
Compressive spectral renormalization method
(Işık University Press, 2018-09-09)
In this paper a novel numerical scheme for finding the sparse self-localized states of a nonlinear system of equations with missing spectral data is introduced. As in the Petviashivili's and the spectral renormalization ...
