Abstract
In this paper we present a calibration method for mitigating the effects of mutual coupling affecting the signal radiated by MIMO radar with collocated antennas. The paper contains the measurement results that verify the proposed method. The improved scan-dependent calibration technique is proposed for elimination of the coupling effect. The experiments with a real X-band antenna array validate the calibration procedure presented in this paper.
