Real‐time aircraft radar simulator for a navy training system

Abstract

A real-time aircraft radar simulation applied in naval training is presented. The implemented algorithm works on a 3D synthesized environment, described by large sets of polygons-a typical scene can have a million of triangles-and the lobe is discretized with a cluster of rays. The radar display is recreated solving fast raypolygon intersections (a variation of Ray-Shooting), and mapping them on the screen. This work proposes a new polygonal simplification method and a geometric classification algorithm in order to solve the intersections efficiently. This methodology leads to high fidelity images and real-time radar simulation, which operates at the specified 15 revolutions per minute rate. The results were tested with trained aircraft pilots. ß

Improving teaching–learning process through ICT methods assisted with CFD techniques for marine engineering courses

“…Following the VLE philosophy, students can obtain on the one side a selected bibliographic pool for tracking the subject, and on the other side, video tutorials for training the proposed projects. For this purpose, a VLE based on the Moodle platform (https://moodle.org/) can be consulted to guide during learning process . The tutorials are made mainly using Camtasia Studio® software, as mentioned above; from the experience during two academic courses, it can be stated that this tool leads to obtain a faster learning.…”

“…It should be noted that rather than focusing on mathematical processes, the aim of engineering training should be focused on the stimulation of modeling and designing creativity . As a relevant advantage, the CFD tool reveals itself as profitable hands‐on tool that can be used in the regarded pedagogical method.…”
