“…There are many types of commercially available surveillance systems for the protection of large-area objects such as harbours, wind farms, and other offshore critical infrastructure [1,4,5,11,13]. However, some observations can be made regarding basic concepts of such systems, because there is a general tendency to include such components as: • radar-visual observation systems with automatic target detection and tracking by a radar, followed by cueing of cameras for visual recognition; • CCTV paired with thermal cameras for day and night observation capability; • fusion of daylight and thermal camera images to obtain easy-to-comprehend output for a system operator; • merging the radar and image data and visualization of the target trajectory on a digital map.…”

Problems regarding the security of maritime infrastructure, especially harbours and offshore infrastructure, are currently a very hot topic. Due to these problems, there are some research projects in which the main goal is to decrease the gap and improve the methods of observation in the chosen area, for both in-air and underwater areas. The main goal of the paper is to show a new complex system for improving the security of the maritime infrastructure by means of many methods of observation – such as thermovision, optical devices, and radar systems – generally by means of an electromagnetic wave as a carrier of information in the air and acoustical methods in water. The system can be applied to the protection of maritime infrastructure as well as the coastal zone.

“…The article includes recommendations and guidance for operators, which are helpful during sonar record interpretation, and mainly focuses on the data obtained during autonomous underwater vehicle (AUV) missions. Previous works related to the subject mostly cover the aspects of side scan sonar data received using towed sonars [11,12]. However, the basic principles of sonar operation are the same.…”

Image acquisition from autonomous underwater vehicles (AUVs) is useful for mapping objects on the seabed. However, there are few studies on the interpretation of data collected with side-scan sonar during autonomous underwater vehicle missions. By recording the seabed with 3D multibeam sonar, a large number of survey points can be obtained. The collected data are processed using applications based on remote sensing image processing. The data collected during AUV missions (or other sonar carriers) needs to be pre-processed to reach the proper effectiveness level. This process includes corrections of signal amplification (Time Varying Gain, or TVG) and geometric distortions of sonar images (Slant Range Corrections). It should be mentioned that, when carrying out the interpretation process for structures on the sea floor, sonar users need to understand the process of visualising seabed projections and depressions, as well as the resolution limitations of the sonar sensors.
