Abstract:

This report presents the results of a contract performed to evaluate the feasibility of a proposed focused synthetic rectangular array for microwave detection and imaging of mines. The proposed technique uses a bistatic antenna system with transmitter and receiver located at the angles of incidence and reflection, respectively of the radiation illuminating the ground. These angles are equal to the Brewster angle of the ground medium so that ground reflections are minimized for vertical polarization. The transmit antennas has a broad beam which illuminates the field of view on the ground. The receiver antenna is a horizontal line array, which forms a rectangular synthetic array by the forward motion of the vehicle. The results of an analytical study are presented, and experimental results are described which give high-resolution three-dimensional images of various types of buried anti-tank mines. A system design for a focused rectangular synthetic countermine array is also given.
