This model course aims to meet the mandatory minimum standards of competence for "use of radar and ARPA to maintain safety of navigation". The course includes the theory necessary to understand the system configuration, principles, performance of shipborne marine radar and ARPA, the factors affecting radar performances, how radar information is obtained, displayed and analysed, the limitations…
