Estimation of Short Range Multiple Coherent Source Location by Using MUSIC Algorithm
Takashi Kato · IEICE Transactions on Communications · 2005
An estimation method of source location of undesired electromagnetic wave from electronic devices by using the MUSIC algorithm is proposed. The MUSIC algorihm can estimate the direction of arrival accurately however, the estimation error is large in the case of short range multiple coherent sources. In order to overcome this problem, a method to improve the estimation accuracy is presented. Experimental results show that the proposed method can reduce the maximum estimation error from 7 cm of the conventional method to 2 cm.
