Space-air-ground-sea integrated network, as a promising networking paradigm for the sixth
generation (6 G) communications, connects satellite networks, aerial networks, terrestrial …

To maximize the transmitted power available in active sensing, the probing waveform should
be of constant modulus. On the other hand, in order to adapt to the increasingly crowed …

The localization and tracking of underwater objects have many applications. In a proactive
underwater sensor array, some nodes will periodically broadcast linear frequency …

This paper presents a new transmitter and receiver placement method for sensing a target in
a region of interest with distributed multiple input multiple output (MIMO) radar systems …

Spectrograms provide an effective way of time–frequency representation (TFR). Among
these, short-time Fourier transform (STFT) based spectrograms are widely used for various …

Underwater acoustic target recognition is an important supporting technology for the
underwater information acquisition and countermeasure, and its core is the target feature …

Underwater target search and tracking has become a technical hotspot in underwater
sensor networks (UWSNs). Unfortunately, the complex and changeable marine environment …

Accurate underwater target recognition is challenged by high noise levels, signal
attenuation, multipath reflections, and the need for efficient real-time processing in complex …

An autonomous underwater vehicle (AUV) can be employed to estimate an underwater
target's position using the Doppler shift measurement extracted from received signals …

This paper proposes a directional transducer-enabled neighbor discovery algorithm in
integrated sensing and communication for underwater acoustic networks (ISAC-UANs). The …
