operators by simulating equipment interfaces in a controlled and predictable scenario; on the other hand, it may simulate non-conventional scenarios to train advanced operators under stresses. As modelling spurious phenomena that yields marine equipment malfunctions is significantly complex, low-fidelity solutions have been proposed to the task. Likewise, the current work is concerned with the development of a low-fidelity radar module to train experienced operators under non-typical conditions. Particularly, this paper describes the radar implementation from the TPN-USP Manoeuvring Simulation Center and presents how simple additional effects may be modelled with considerable simplifications to ensure real-time performance. The implementation may be replicated in any ship manoeuvring simulator based on the game engine Unity3D.
