Because of the importance of maintaining safety at sea, great training efforts are required to ensure that operators act safely in any ship. In such context, ship manoeuvring simulators are used to ease operators' learning experience. On the one hand, it may assist in the education of new 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.

SYMDAS : Raw Data Simulator for the Radar with Electronically Controlled Beam

Mazurek G.

International Journal of Electronics and Telecommunications

2011

Vol. 57, No. 4

473-476

The subject of the paper is the software simulator of baseband signals received in a radar. These synthetic signals are sent to the DSP unit responsible for target detection and estimation. The software has been developed in Warsaw University of Technology as a part of R&D project, and its main purpose is to allow flexible testing and validation of the algorithms running in DSP processors of the new radar.

A New Algorithm for Phased Array Radar Search Function Improvement in Overload Situations

A new algorithm is proposed for phased array radar search function resource allocation. The proposed algorithm adaptively priorities radar search regions and in overload situations, based on available resources, radar characteristics, maximum range and search regions, optimally allocates radar resources in order to maximize probability of detection. The performance of new algorithm is evaluated by the multifunction phased array radar simulation test bed. This simulation test bed provides capability to design and evaluate the performance of different radar resource management, target tracking and beam forming algorithms. Some results are presented that show capabilities of this simulation software for multifunction radar algorithms design and performance evaluation.
