right arrow 16 Course Description

Radar is one of the essential components of modern navigation as it provides a picture of the vessel’s surroundings, through independent means, during the day, at night and in nearly all kinds of environmental conditions.

To understand the potential and limitations of radar systems, it is crucial for the user to know the technical basics. The radar working principle and the fundamentals about radar radio waves are therefore described in full. The functioning of the main components of radar systems is explained and the process of digitalisation and imaging elucidated. An insight is given into detection, size, shape, and the extent of targets.

right arrow 16 Course Objectives

The aim of the course is to provide technical background knowledge that enables operators to fully understand the potential, as well as the limitations of radar and ARPA equipment on-board.
