The system identification method is applied to the wideband mutual coupling compensation of receiving arrays. Using the receiving mutual impedances of an antenna array calculated at different frequencies, a multi-port compensation network is identified for wideband mutual coupling compensation. The identified network transfer function matrix is shown to be able to compensate the frequency-dependent mutual coupling effect accurately. Results obtained in a wideband direction finding experiment demonstrate the validity and effectiveness of the proposed method.
