Sonar ground
WebA ground-penetrating tunnel-detecting active sonar launches two different monotonic acoustic beams down into the ground from the surface. If the two separate monotonic acoustic waves arrive at a stress field, they will mix and produce a frequency difference heterodyne due to the inherent pressure nonlinearities in the solid medias.
