摘要

Since there are problems that the peripheral equipments do not operate appropriately due to undesired radio wave emitted by electronic equipment, it is important to estimate the location of radiating source to overcome such EMC problems. We study estimation method of the electromagnetic source location by using the MUSIC algorithm. Usual MUSIC algorithm is covering the electromagnetic source location in the infinite distance. However, we employ MUSIC algorithm at the distance of a few wavelengths from the electronic equipment. In this paper, the estimation characteristics of short range electromagnetic source by using MUSIC algorithm is presented, and estimation accuracy is shown.
