Summary :

For grasping the electromagnetic environment, the visualization as a pattern of electromagnetic field distribution is effective. Generally, the electromagnetic field distribution pattern is composed of several fields caused by different electromagnetic wave sources. In this paper, a method of pattern decomposition of overlapped electric field pattern is proposed. This method is based on the least square estimation of intensity of electromagnetic wave sources under the assumption that the location of every source has been given. The estimation formula of electric field intensity of sources is derived. This method is applied to decompose the real patterns measured in semi-anechoic chamber. These experimental results show that the method of pattern decomposition can be used to eliminate or extract the unwanted reflected and scattered field with less error.
