The motion of a self-propelled body excites internal waves that modulate wind-induced
microscale waves and affect the radar scattering cross section of rough sea surfaces. This …

In this study, a refined and improved theoretical model was proposed for calculating the
synthetic aperture radar (SAR) images of internal wave wakes. This model was based on an …

在实际海洋中由于太阳的照射以及盐度在空间分布的差异使得海水密度分布不均,
在深度上形成密度梯度变化的密度跃层. 当水下航行体在海洋中航行时, 会对背景流体产生扰动 …

The characteristics of underwater vehicle wakes are intricately linked to multiple parameters,
such as speed, depth, and environmental factors. Obtaining wake characteristic information …

Spectrograms provide an efficient way to analyze surface elevation signals of ship waves
taken from a sensor fixed at a single point in space. Recent work based on a simplified …

The spectrogram, based on a short-time Fourier transform, can visualize the time-dependent
frequency spectrum of waves and is easy to compute. This time-frequency analysis method …

The fluid density commonly stratifies in the ocean due to the vertical distribution of
temperature and salinity. Coupled with a certain source of excitation, the surface wave and …

Internal waves induced by an underwater self-propelled body expose its existence by
changing the sea surface roughness. This study employs short-time Fourier transform to …

The density stratification of seawater leads to the generation of internal wave wakes as a
submerged body moves, and the characteristics of these wakes are closely related to the …
