Underwater Acoustic Modem- Challenges, Technology and Applications - A Review Survey
Today, underwater acoustic communication is developing for its various applications. For signal transmission in underwater using ocean/ sea/lakes/rivers as a medium an appropriate underwater acoustic system is required. The significant characteristic of ocean makes the underwater communication difficult using electromagnetic waves. The characteristics of an acoustic signal make a good candidate...
متن کاملEvaluation of underwater acoustic propagation model (Ray theory) in a river using Fluvial Acoustic Tomography System
Underwater acoustics is widely used in many applications, such as oceanography, marine biology, hydrography, fishery, etc. Different models are introduced to simulate the underwater acoustic propagation in the oceans and the seas. In this study, the Ray Theory model is used to simulate the acoustic wave propagation in a shallow-freshwater river (Gono River) located in western part of Japan. The...
متن کاملUnderwater Acoustic Target Tracking: A Review
Advances in acoustic technology and instrumentation now make it possible to explore marine resources. As a significant component of ocean exploration, underwater acoustic target tracking has aroused wide attention both in military and civil fields. Due to the complexity of the marine environment, numerous techniques have been proposed to obtain better tracking performance. In this paper, we sur...
متن کاملAdvanced Underwater Technology with Emphasis on Acoustic Modeling and Systems
The Sonar Performance Prediction System (SPPS) will be introduced. The SPPS is an integrated ocean-acoustic propagation model coupled with a sonar performance prediction model. A stationary sea surveillance sonar consisting of a horizontally nested hydrophone array and a vertical transmitting/ receiving array may be used lo dctcct, localisc and track surface and subsurfacc contacts within its c...
متن کاملUnderwater Multi-Vehicle Trajectory Alignment and Mapping Using Acoustic and Optical Constraints
Multi-robot formations are an important advance in recent robotic developments, as they allow a group of robots to merge their capacities and perform surveys in a more convenient way. With the aim of keeping the costs and acoustic communications to a minimum, cooperative navigation of multiple underwater vehicles is usually performed at the control level. In order to maintain the desired format...
