Test of Vehicle Positioning by Triangulation with Infrared Signal-Direction Discrimination

摘要

Utilizing two one-dimensional infrared signal-direction discriminators mounted on a vehicle with a lateral separation between them to measure the coming directions of the signal emitted from another target vehicle, the position of the target vehicle relative to this detecting vehicle can be located by triangulation. The one-dimensional signal-direction discriminator is composed of two planar receiving modules forming a specific geometric structure which leads to different responsivities of these modules for a signal incident from a definite direction. The coming direction of the signal is determined by comparing the signal strengths received by these individual receiving modules. The basic concept of such a short-range vehicle-to-vehicle positioning system together with a rudimentary implementation are presented in this paper. The measured results reveal the feasibility and applicability of this method.
