Reconstructed 2D MIMO Using Burg Algorithm

In this paper, the Burg algorithm is used in order to extrapolate the elements of 2-D multiple-input multiple-output (MIMO) array. The goal is to achieve higher angular resolution beyond that of the equivalent 2-D MIMO virtual aperture. It is shown that the size and number of elements of the MIMO physical array can be significantly reduced. The experimental methodology used to acquire 3-D data using a 1-D MIMO radar is described. The experiments use a commercial-off-the-shelf 1-D MIMO radar system. Using this approach, the antenna configuration used can be tested experimentally in cases where it is not possible to manufacture a 2-D MIMO antenna array or when it is desired to observe the antenna response prior to fabricating the antenna.
