Underwater acoustics has been implemented mostly in the field of sound navigation and
ranging (SONAR) procedures for submarine communication, the examination of maritime …

Considering heterogeneities and difficulties in the classification of underwater passive
targets, this paper proposes the use of Local Wavelet Acoustic Pattern (LWAP) and Multi …

With the rapid development of underwater sensor techniques, using acoustic techniques to
obtain and analyze underwater images is an effective approach due to the superior nature of …

Currently, the use of intelligent systems for the automatic recognition of targets in the fields of
defence and military has increased significantly. The primary advantage of these systems is …

This paper proposes a method to enhance the quality of detecting and classifying surface
vehicle propeller cavitation noise (VPCN) in shallow water by using the improved Detection …

Recently, side scan sonar (SSS) is increasingly applied to underwater search, which can
display the microgeomorphic morphology and distribution, and obtain a continuous two …

This paper considers passive broadband underwater source detection which is more
practical but also more challenging than narrowband detection. Typically, broadband source …

Passive sonar is widely used for target detection, identification and classification based on
the target radiated acoustic signal. Under the influence of Doppler, generated by relative …

Sažetak Signal processing in hydroacoustic system will be presented in this paper. The
research results, depicted in this article, were achieved during realization one of the stages …

The unstable geometric features affect the accuracy of object detection in sonar images. We
thus propose a novel multi-level feature enhancement network to enhance useful features …
