The DOA Estimation Method With Calibration Matrix Selection Using Inner Product
Jun Yaezawa, Hiroyuki Arai (Yokohama National Univ.) AP2008-78
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we present the DOA estimation method with calibration matrix selection in the case of simple calibration methods are not available because the array elements can not approximate a single mode and the mutual coupling between array elements has an unknown angle dependency.
The proposed method derives an optimum calibration matrix in a measurement environment by calculating an inner product between calibrated eigen vector of the signal subspace and ideal mode vectors in the database.
We show the effectiveness of the proposed method in 1-D and 2-D DOA estimation and the reduction methods of database and computation load by experiment in anechoic chamber.
