Development of Oceanic Engineering based on Radar/Sonar/optical Technology

Introduction

Radar, sonar and optical devices are the most common devices for oceanic engieering. The exploration and development of marine resources, communication and navigation, underwater target detection and recognition, environmental monitoring and natural disaster prediction all depend on oceanic engineering technology based on radar, sonar and optical technology. The development of oceanic engineering technology needs all kinds of radar/sonar/optical sensors and related signal processing technology to provide support. Radar/sonar/optical sensor can be installed on fixed platforms such as buoy and submarine similar to underwater anchoring, or on mobile platforms such as underwater robot and ship. Multiple sensors are often networked to effectively explore, observe, and utilize the ocean. The transmission characteristics of signal will be affected by many factors, such as propagation loss, multipath effect, Doppler effect, time-varying channel and so on. In addition, the radar/sonar/optical sensor network also have problems such as sparsity, limited energy of sensor nodes, unstable topology and transmission, which seriously reduces the performance of underwater acoustic communication, navigation, positioning, environmental perception, array processing and signal detection based on the sensor network. Therefore, it is the key of radar/sonar/optical sensor and network technology to realize the effective acquisition of ocean information through advanced signal processing technology considering transmission characteristics of underwater acoustic and reliability of sensor network. In this Special Thematic Issue, relevant experts are invited to report the latest progress in the oceanic engineering field. This includes underwater communication, navigation, positioning, environmental perception, array processing and signal detection, remote sensing, tomography, ocean filed monitoring and so on.
