Abstract

A beam forming array is investigated for use in a radar system that is part of a hybrid acoustic/electromagnetic technique for detecting land mines. The radar is used to measure the surface displacement of the earth due to acoustic waves in the earth. The beamforming array is used to obtain small spatial resolution of the measurement of the displacement while allowing an adequate standoff distance for the radar. The tradeoffs between the resolution and the sidelobes of the array are investigated. Finite-difference time-domain and experimental models have been implemented to examine the feasibility of the beamforming array.
