This paper describes the procedure for obtaining ground prospections using seismic-acoustic signals, oriented to the detection of buried objects located at the ground surface. The presented methodology uses a Helmholtz resonator as the source of perturbation and a set of omnidirectional microphones used as sensors for detecting reflections of the superficial Rayleigh waves. The results show that the methodology is able to provide ground images where the buried object can be easily detected, both in plain as well as in uneven surfaces.
