Mutual coupling effects and their reduction in wideband direction of arrival estimation
Krishna M. Pasala, Edward M. Friel · IEEE Transactions on Aerospace and Electronic Systems · 1994
The performance of multiple signal classification (MUSIC) algorithm using three different inputs over a wideband of frequencies is considered. These inputs are: 1) ideal voltages, 2) actual voltages which include coupling effects and are obtained with the method or moments, and 3) corrected voltages which are obtained from the actual voltages so that the mutual coupling effects are removed. Linear arrays of dipoles, sleeve dipoles, and spiral antennas are considered over 200 MHz to 400 MHz band.>
