Ground penetrating radar imaging with a simple MIMO array

A simple Multiple-Input Multiple-Output antenna array for ground penetrating radar imaging is presented in this paper. The antenna array only consists of a linear transmit array composed of four antennas and a linear receive array composed of six antennas. The length of this array is about 90cm and the width is 12cm. An algorithm named modified Kirchhoff Migration is adopted, and 2-D and 3-D imaging simulations of three ideal scattering points ware implemented to prove its practical applicability in the end. It is shown that focused images can be obtained with the simple MIMO array for the ground penetrating radar imaging.
