The acquisition of propeller signals can be applied to localization and fault diagnosis, etc.
However, recording a large amount of propeller signals results in higher costs. Compressive …

In magnetic resonance (MR) image reconstruction, the orthogonal matching pursuit (OMP) is
widely recognized for its simplicity and competitive performance. However, OMP designs a …

In the shallow-water waveguide environment, the tonal signals radiated by moving targets
carry modal interference and Doppler shift information. The modal interference can be used …

Multiple Frequency-Shift Keying (MFSK) has been used widely for underwater acoustic
communications due to its low complexity and channel robustness. However, the traditional …

Channel estimation in Underwater Acoustic Communication (UAC) faces significant
challenges due to the non-Gaussian, impulsive noise in ocean environments and the …

Traditional Doppler velocity estimation method usually requires radiant noise in a high
energy line spectrum, which is often less effective for a target without an obvious line …

With the aim of solving the problem of identifying complex underwater acoustic targets using
a single signal feature in the Time–Frequency (TF) feature, this paper designs a method that …

A cognitive waveform design is proposed for use in SONARs (Sound Operated Navigation
and Ranging) for detecting targets in undersurface environment. The study adopts a …

Passive radial velocity estimation based on a single hydrophone has a wide range of
applications in engineering, and can be used in small underwater platforms such as …

In the context of torpedo guidance systems, the performance of active sonar in channel
parameter estimation and target detection and recognition is significantly degraded by the …
