ARL-TR-8625 - Measurement of the Acoustic-Radar Response of Electronics and Metals by Excitation with a Modal Thruster in a Transverse Electromagnetic Cell | U.S. Army Research Laboratory

摘要

A novel technique for exciting radar targets with acoustic and electromagnetic (EM) energy simultaneously is presented. The technique exploits the interaction between the two forms of energy at the target, in a well-controlled acoustic and EM environment, to evaluate the feasibility of standoff acoustic-radar detection of each target. Data recorded on three electronic radar targets and three metallic clutter items, probed by audible acoustic frequencies and UHF radio frequencies, successfully demonstrate acousto-EM interaction.
