A Proposal of Anti-Collision System between a pedestrian/motorcycle and vehicle using Radio Wave DOA Estimation by MUSIC and Unitary ESPRIT methods

摘要

The purpose of this study is to establish a distributed system without an infrastructure for avoidance of traffic accidents between vehicles and pedestrians or motorcycle. In the model of blind spot in roadway, we assume that a vehicle has an array antenna as a receiver and a pedestrian or motorcycle has a transmitter. We carry out the analysis of radio wave propagation using the ray tracing method and then, we estimate the direction of arrival of radio wave using MUSIC and Unitary-ESPRIT methods. We show that a vehicle could detect the pedestrian or motorcycle behind the obstacles.
