Underwater acoustic target recognition (UATR) technology has been implemented widely in the fields of marine biodiversity detection, search and rescue, seabed mapping, providing an essential basis for human economic military activities. With rapid development machine-learning-based acoustics field, these methods receive wide attention display a potential impact on UATR problems. This paper revi...

Underwater acoustic communication is a core enabling technology with applications in ocean monitoring using remote sensors and autonomous underwater vehicles. One of the more challenging underwater acoustic communication channels is the medium-range very shallow warm-water channel, common in tropical coastal regions. This channel exhibits two key features-extensive time-varying multipath and hi...

Recent progress in underwater robotics and acoustic communication has led to the development of a new paradigm in ocean science and technology, the Autonomous Ocean Sampling Network (AOSN). AOSN consists of a network of fixed moorings and/or autonomous underwater vehicles (AUV) tied together by state-of-the-art acoustic communication technology. The Generic Oceanographic Array Technology System...

Passive acoustic monitoring (PAM) is widely in use to study marine mammals in their underwater habitats. Since marine mammals can be found in all ocean basins, their habitats cover diverse underwater environments. Properties of the ocean environment, such as sound speed profile, bathymetry, and sediment properties can be markedly different between these diverse habitats, leading to differences ...

Underwater acoustic communication (UWAC) is often the only viable solution to establish an ad-hoc underwater communication network. The specific features of UWAC, arising from the physics of underwater acoustics, make the design of resource-efficient media access control (MAC) protocols important as well as challenging. In this paper, we tackle this task considering ad-hoc UWAC networks that su...

Robotic vehicles working in new, unexplored environments must be able to locate themselves in the environment while constructing a picture of the objects in the environment that could act as obstacles that would prevent the vehicles from completing their desired tasks. In enclosed environments, underwater range sensors based off of acoustics suffer performance issues due to reflections. Additio...

As underwater communications adopt acoustics as the primary modality, we are confronting several unique challenges such as highly limited bandwidth, severe fading, and long propagation delay. To cope with these, many MAC protocols and PHY layer techniques have been proposed. In this paper, we present a research platform that allows developers to easily implement and compare their protocols in a...

hen someone is new to the IEEE Signal Processing Society (SPS) and asks how to get involved with the community, a seasoned member will readily suggest that one starts out by joining a technical committee (TC). True, a TC is the home of a technical community, and it is essential for community building. Let's turn the clock back about 40 years, to when the first IEEE International Conference on A...
