Abstract
This paper presents a novel angle of arrival (AoA) detection scheme by using phase differences of electromagnetic waves. Towards its practical utilization, our focus is placed on how to realize a fading tolerant AoA scheme. What is the most important aspect from the practical point of view is to allow the proposed scheme to find the high-speed direction of electromagnetic waves without requiring there time measurement. Another focus lies in realizing the scheme by developing an in-house AoA detector prototype. The implementation details are explained in this paper, and experimental results show that the proposed scheme and the developed prototype can be considered quite satisfactory for mobile robot navigation in a door environment.
