Résumé / Abstract

This article describes a novel approach to the real-time visualization of 3D imagery obtained from a 3D millimeter wave radar and the associated sensor fusion modules. The MMW radar system uses two scanning beams to provide all weather 3D distance measurements of objects appearing on the ground. This information is displayed using our high-end 3D visualization engine capable of delivering models of up to 100,000 polygons with 30 frames per second. The resulting 3D models can then be viewed from any angle and subsequently processed to integrate match them against 3D model data stored in a synthetic database. Such systems can be installed in aerial vehicles in order to process and display information merged from multiple image sources including a high-resolution MMW 2D and 3D radar images, a stored terrain with 3D airport database, and near IR sensors. The resulting system provides safe all-time/all-visibility navigation in terrain-challenging areas and, in particular, real-time object detection during landing. This paper focuses on the real-time imaging and display aspects of our solution, and will discuss technical details of the radar design in the context of a practical application.
