Currently, marine radar simulators are widely used by the members of IMO as one of many useful tools for seafarer education and training (Ali 2006 Organization 2006 Teel et al. Upon completing all requirements set forth in the training, the trainee will receive certification for qualifications to work on board.

A marine radar simulator is the only acceptable approach in the laboratory for seafarers to learn how to operate radar equipment and use radar for positioning, navigation, and anti-collision. The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers 78/95 (STCW Convention 78/95) of International Maritime Organization (IMO) requires using a marine radar simulator to train seafarers. Keywords: Marine radar simulator, Coastline echo, Fractal algorithm
However, imperfections with currently available marine radar simulators require simulator developers to make improvements.Ĭase description: In this study, improved fractal algorithms (random Koch curve, fractional Brownian motion, and Weierstrass-Mandelbrot function) are applied to generate natural-looking radar echoes on a marine radar simulator.ĭiscussion and evaluation: From the results of the simulations, we can observe that the structures of the coastline echoes generated by improved fractal algorithms, especially by fractional Brownian motion algorithm, outperform the echoes generated by conventional method in representing a natural coastline feature.Ĭonclusions: Based on evaluations from a panel of experienced mariners, we conclude that the coastline echoes simulated by fractal algorithms better represent a natural coastline feature than those generated by conventional methods. To fulfill all of the marine radar simulator training requirements, a high performance simulator is necessary.
