Experimental comparison of multi-static and mono-static antenna arrays for subsurface radar imaging

The performance of multi-static and mono-static radar systems is compared using experimental setup consisting of linear drives that move transmit and receive antennas in the programmable positions corresponding to multi-static or mono-static linear antenna arrays. The synthetic aperture in the direction perpendicular to the imitated linear arrays is formed by moving the target by an additional linear drive. Simulated and experimental radar images are obtained for various multi-static antenna configurations, and compared to their mono-static equivalents. The mono-static and multi-static signal processing technique is given. Possible applications of the described experimental technique are suggested.
