Moving Ground Target Detection With Seismic Signal Using Smooth Pseudo Wigner–Ville Distribution

IEEE Transactions on Instrumentation and Measurement, 2020
The main challenging task in moving ground target detection with seismic signals is the extraction of robust feature vectors for accurate localization of a seismic event.

The short-time Wigner-Ville distribution associated with linear canonical transform

International Conference on Signal Processing Systems
This article proposes the unified short-time Wigner-Ville distribution (USWD) and explores its various properties, which is a generalized integral transform suitable for time-varying signals with varying features.

Lamb Wave Mode Decomposition Based on Cross-Wigner-Ville Distribution and Its Application to Anomaly Imaging for Structural Health Monitoring

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2019
Lamb waves are characterized by their multimodal and dispersive propagation, which often complicates analysis. This paper presents a method for separation of the mode components and reflected components in sensor signals in an active structural health ...

Multichannel maximum-entropy method for the Wigner-Ville distribution

, 2020
The Wigner-Ville distribution is a powerful technique for the time-frequency spectral analysis of nonstationary seismic data. However, the Wigner-Ville distribution suffers from the cross-term interference between different wave components in the seismic

Spectral Decomposition of Seismic Data With Variational Mode Decomposition-Based Wigner–Ville Distribution

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
Wigner–Ville distributions (WVDs), which provide superior time-frequency resolution and energy distribution concentration relative to other traditional Fourier-based or wavelet-based seismic time-frequency methods, are an important tool for spectral ...
