Abstract

A near-field beamforming array is investigated for use in a radar system that is part of a hybrid elastic/electromagnetic technique for detecting land miens. The radar is used to measure the displacement of the surface of the earth and land miens due to elastic waves in the earth. The beamforming array is used to obtain a sufficiently small spatial resolution for the measurement of the displacement while allowing an adequate standoff distance for the radar. Both theoretical and experimental models are developed to investigate the viability of the beamforming array.
