Focusing patterns within far and near field for a novel 2D sparse MIMO array

A novel sparse 2 dimensional (2D) multiple-input-multiple-output (MIMO) array topology is proposed for 3D imaging. The highly compact, novel array only consists of 2 transmitters and 8 receivers. The focusing capabilities of the array are investigated by simulation and measurement data. The results for the focusing capabilities show that the array has a favorable maximum sidelobe level within far and near field.
