Abstract:Estimation of wave source position is important technique for searching unknown noise source in electromagnetic compatibility measurement. In this article, a new position search technique for unknown wave sources is proposed by using the spherical vector wave function and point-matching method. In this technique, a few virtual boundaries are placed on surrounding areas, which includes the unknown wave sources. In order to verify the validity of the method, a new demonstrative measurement system is developed and used for experiments in the microwave band. As a result, the position of unknown wave sources can be estimated accurately by using the proposed method.
