An imaging method for MIMO radar with sparse array based on Compressed Sensing

The number of antenna elements in MIMO (Multiple-Input Multiple-Output) radar is too many when imaging for moving targets with single snapshot. To a i m at solving the problem, an imaging method for MIMO radar with sparse antenna array is proposed. Firstly the configuration of sparse antenna array is analyzed. Then, combining Compressed Sensing theory, a novel imaging method for MIMO radar with sparse array is put forward. Single snapshot imaging for moving targets is implemented by this method, which not only can avoid the difficulty of motion compensation aroused by the targets´ maneuver, but also can reduce the number of antenna elements. Finally, the effectiveness of this method is validated by the simulation results.
