Abstract

In this paper, 2-D MIMO antenna arrays suitable for high resolution burden surface imaging radar operating in frequency band 24-26GHz are proposed. In order to eliminate the cross-range resolution degradation when the antenna beam radiates to the burden surface in nonperpendicular angle, MIMO antenna arrays with elliptical cross-section beam are specially designed. To suppress the high side lobe level of these designed MIMO arrays, two MIMO array sparse methods by symmetrically sparse the arrays with denser elements in the centre and sparse elements around are presented and analyzed. Patterns of the designed MIMO arrays are simulated, which verified the effectiveness of the MIMO arrays for burden surface imaging.
