Abstract

A kind of efficient imaging method for MIMO radar under sparse array based on matrix completion (MC) is proposed in this letter. Based on the uniform transmitting antenna array and the sparse receiving antenna array, the low-rank quality of sparse receiving signal matrix is analyzed. The unknown data of each range unit is estimated with the MC principle and the receiving signal matrix can be exactly recovered. The problem is solved that the MC principle would be deactivated by column/row data loss. And the imaging quality is stabilized while inducing the number of antenna. The result of experiments demonstrates the proposed method, which is aimed at imaging of MIMO radar under sparse array, is suitable for different sparse degree and achieves imaging with the signal snapshot availably.

Key words： MIMO radar; sparse array; matrix completion; signal snapshot imaging
