Special Issue Information

Dear Colleagues,

As the technology for ocean development advances, underwater acoustic communication and detection technology has been widely used in marine environmental monitoring, marine resource development, and underwater vehicle/manned submersible operations. However, underwater acoustic channels have complex characteristics of time–space–frequency variation. To overcome the impact of adverse underwater acoustic channel conditions, it is necessary to explore and develop many technologies. Therefore, in order to promote the development of underwater acoustic communication and detection, we are organizing a Special Issue on underwater acoustic communication and detection, inviting experts and scholars to share their research results, the latest developments in this field, and prospects for future development.

High-quality papers related to various aspects of underwater acoustic communication and detection technology are encouraged for publication, particularly in the following areas.

  • Underwater acoustic communication and detection;
  • Underwater acoustic signal processing;
  • Sonar system design and implementation;
  • Doppler estimation and compensation;
  • Channel estimation and equalization;
  • Intelligent information processing;
  • Signal modulation and demodulation.

High-Resolution Imaging of Targets Using Broadband Acoustic Orbital Angular Momentum Waves and Modal-Domain Focusing Beamforming

Abstract
Applying the acoustic orbital angular momentum (AOAM) wave for underwater imaging can yield richer differential target echo information, a consequence of its spiral wavefront phase and multiple mutually orthogonal modes.

Applying the acoustic orbital angular momentum (AOAM) wave for underwater imaging can yield richer differential target echo information, a consequence of its spiral wavefront phase and multiple mutually orthogonal modes. In broadband AOAM wave imaging, the resolution of conventional beamforming is very low. Although sub-band processing can improve resolution, it cannot handle coherent signal sources. To further enhance the resolution of broadband AOAM wave underwater imaging and address the imaging issue of coherent signals in practice, this paper proposed a modal-domain focusing beamforming method. This paper initially established the echo signal model of broadband AOAM waves based on a uniform circular array. This was followed by the derivation of the beam output signal model. Finally, a new modal-domain focusing transformation matrix was constructed. Numerical results show that the proposed method reduces the background level of the beam pattern to −86dB in simple coherent target source imaging, compared with −40dB for sub-band methods and −70dB for plane wave focusing processing. Furthermore, under different noise conditions, the proposed method achieves high-resolution imaging of complex structures and good imaging of details. Full article

In this paper, we propose a generalized-chirp spread spectrum (G-CSS) that can have various modulation orders and offers superior bit error rate (BER) performance to improve the communication performance of existing chirp-based modulation/demodulation schemes. The proposed G-CSS sets frequency bins with different modulation orders at the start and end points of the symbol and selects frequency bins based on the bits to be transmitted, modulating the signal using corresponding chirps. Therefore, the proposed method allows for independent design of modulation orders at the start and end of the symbol, enabling signal design and flexible transmission tailored to the transmission rate required by the system. Through computer simulations and practical ocean experiments, we compared and analyzed the BER performances of the proposed G-CSS with existing up/down-CSS and long-range CSS (LoRa-CSS). The proposed G-CSS demonstrated a superior BER performance at the same transmission rate. Full article

Based on experimental data from the deep-sea sound channel axis in the Western Pacific, the statistical distribution law of cluster structure and channel delay spread characteristics are analyzed for three typical receiving depths near the sound channel axis in this paper. A ray theory-based underwater acoustic channel model is used to explain the variations in channel parameters over time and the receiving depth. The results indicate that the underwater acoustic communication channel at the channel axis depth over a 20-km range exhibits a clustered structure that depends on the emission angles of sound rays. For the amplitude characteristics, the amplitude of each cluster follows an inverse Gaussian distribution, with the maximum average amplitude observed when the receiver and transmitter depths are similar. The amplitude of each cluster fluctuation decreases as the receiving depth increases. Regarding delay spread characteristics, the delay spread of each cluster, as well as the maximum and root mean square delay spread of the channel, conform to a Gaussian mixture distribution. The mean and fluctuation of the delay spread parameters increase with the receiving depth. Variations in the cluster structure and channel delay spread characteristics above are primarily attributed to the time-varying sound speed along the propagation paths of sound rays emitted at small upward angles.
