Abstract

We propose a new method for finding the direction of arrival (DOA) of the electromagnetic waves emitted from a partial discharge source using Bayesian Network. The time delay between two antennas computed from digital data generally has error because of the effect of sampling time. Therefore the angle of arrival estimated from the time delay also has the estimation error. In order to deal with the estimation error, we investigate a probabilistic method of reasoning with uncertain information. In this method, system provides the probabilities of each angle based on Bayes' Theorem. From results of a simulation and an experiment, we have confirmed that our proposed method is able to estimate the angle of arrival of the electromagnetic waves.
