CASE STUDY: USE OF SAR DATA FOR THE OPERATIONAL CONTROL OF FISHERING SHIPS POSITIONING

Possibilities, elaboration and implementation of test techniques of fishering ships geographic positioning control using SAR data are presented. The main task is the feasibility study of a technology of operational use of SAR data for the detection of positioning fraud by fishering ships. A prototype automated technique is described allowing for the integration of SAR data into the existing industrial monitoring system and complementing other information available in the system to raise the efficiency of ship positioning control. Results of field experiments conducted to evaluate the suggested technology are presented. Various factors such as incidence angles, polarization, and hydrometeorological parameters, influencing manifestation of ships in SAR images are discussed. A suggestion is made that under certain conditions, image synthesizing procedures result in blurring out ship imprints in the images.
