In this paper, the compressive sampling (CS) method is used for two-dimensional (2-D) direction finding (DF) multiple-input multiple-output (MIMO) radar, since the direction angles of targets can construct a sparse vector in the angle space. It is obvious that dividing the angle space is very important for this method. Thus, we derive the resolution limit, which is employed in dividing the angle space. Finally, the simulated results validate that the resolution limit is important to the division of angle space when using CS algorithm. (4 pages)
