Recognition of Radar Signals Modulation Based on Short Time Fourier Transform and Reduced Fractional Fourier Transform ⋆

As the useful time-frequency tool, the Fractional Fourier Transform (FRFT) and the Short Time Fourier Transform (STFT) have a great development of signal recognition. And the Reduced Fractional Fourier Transform (RFRFT) was recently proposed and has been used in the recognition and estimation of chirp signals. A new method based on STFT and RFRFT is presented for radar signals modulation recogn...

On short-time Fourier transform with single-sided exponential window

A special case of the short-time Fourier transform with single-sided exponential window, named exponentially forgetting transform (EFT), is discussed. It is shown that the EFT offers in a certain sense good time-frequency resolution and that stable reconstruction of a signal from samples of the EFT at equidistant time-frequency grid points (nT, kSZ) is possible, even for the case of nonredundan...

Real-time Denoising of Ae Signals by Short Time Fourier Transform and Wavelet Transform

Laser AE method is a non-contact AE detection technique, which utilizes laser interferometer as sensor. This method is less subjected to environmental difficulties and can be adaptive for wider target than conventional PZT sensors. However, laser AE method has to improve its sensitivity because the noise level of laser interferometer is higher than PZT sensors. In this study, a method to reduce...

Nonlinear Integrable Equations and Nonlinear Fourier Transform

In this paper we study nonlocal functionals whose kernels are homogeneous generalized functions. We also use such functionals to solve the Kortewegde Vries (KdV), the nonlinear Schrödinger (NLS) and the Davey-Stewartson (DS) equations. The solution of certain integrable equations in terms of formal power series was obtained in [4], [5]. In these papers the solution was expressed in a formal pow...
