近年の様々な電子通信機器の発達、普及に伴い、それらの機器からの不要電磁波による機器間の電磁波干渉の問題が深刻化している.その対策として不要電磁波の波源位置を特定することは非常に重要である.電磁波放射体の波源位置を推定する手法としては以前より,電流値を用いて推定する手法,合成開口法を用いる手法,電波ホログラムを用いた手法などが多数提案されている.%Estimation of wave source position is important for suppressing the emission of unwanted waves from electronic devices. Previously, a position estimating method for unknown wave source was proposed by using spherical wave function. However, this method targeted symmetrical wave sources located on z-axis. Therefore, this report proposes a new extended method for estimation of asymmetrical wave source. In order to verify the validity of this method, we experimented with three different antennas as wave source and estimated the position of wave source. As result of them, we can estimate position of wave source accurately.
