要約(日本語): We propose a method to estimate the number of partial discharge sources in multipath environment using the multichannel blind deconvolution method called the super-exponential deflation method. The super-exponential deflation method can extract the source signals one by one from the observed signals. The proposed method estimates the number of sources by repeating the signal extraction and analyzing the eigenvalues using the criterion function to distinguish the presence or absence of the source signals in the observed signals. The effectiveness of the proposed method was demonstrated in FDTD simulations where three signal sources, four metallic bodies and square array antennas were set.
