Abstract

The calibration of a collocated MIMO radar is addressed by means of independent calibration of transmit and receive arrays. The solutions for both arrays' elements gain and phase terms only and the full coupling matrix estimation are presented. The proposed solution significantly improves over the conventional calibration of the virtual array in terms of calibration accuracy and reduced measurements requirement, as demonstrated by numerical simulation and validated by calibration of a commercial automotive radar.
