摘要：

A new and practical method is proposed to compensate for the mutual coupling effect in a dipole array deployed for direction finding. This method does not require the known current distributions on the antenna elements or the known elevation angles of the incoming signals. A new definition of mutual impedance is introduced to characterize the effect due to mutual coupling between dipole elements. The new mutua I impedances are calculated based on an estimated current distribution. It is shown that current method has a significantly better ability to compensate for the mutual coupling effect than previous methods. Computer simulations using the MUSIC algorithm are provided to demonstrate this method.
