The monitoring of changes in the shape of sea bottom in order to control the depth is one of the basic methods of ensuring safety of navigational units. The geostatistic method is counted among the best numerical methods of surface spatial modelling. The construction of a spatial model requires the interpretation of measurement data in order to determine the depth for any coordinates, e.g. in nodes...
This article deals with a method of vessel position determination based on underwater information. The method consists in processing images produced by hydroacoustic systems. The system of bathymetric position determination can be a source of navigational information supplementary to satellite navigation, or the only source in most cases of submarine navigation. Information received from the second...
The article presents the concept of applying sonar images for determining a vessel’s position. A modified method of logical product has been presented, which enables the matching of the lateral sonar’s image to the standard.
The latest international trends aim at the introduction of the requirement of automatic tracking in all marine navigational radars. This necessitates further improvement of methods for target state estimation. This article presents the results of research into the neural method using double artificial neural networks of the GRNN type.
