Calibration of dipole array with reflector using method of images

Recently, implementation of super-resolution technique for high-resolution direction-of-arrival (DOA) estimation has been expected in application of smart antenna and wireless propagation research fields. However, to realize high-resolution performance of the techniques, array calibration is indispensable. Generally, array calibration becomes difficult when there exist conductive object close to the array elements. A dipole array with reflector plate is one of the popular arrays. The calibration becomes difficult for the array with finite size of the reflector In this report, we propose a new calibration technique by using method of images, and show that the technique is available for arrays with reflector by computer simulations and experiments.
