The issue of humanitarian demining becomes increasingly important in the modern world. In the light of this, one of the most urgent problems to be solved is the development of new more effective and safer methods of land mine detection. The idea, which forms the essence of this paper, is based on using scattering of Rayleigh surface waves on buried land mines for their remote detection (at distances of 5-10 m). Rayleigh waves at frequencies 0.1 - 1 kHz seem to be a natural physical tool for this purpose. Unlike electromagnetic waves, they are equally sensitive to both metallic and non-metallic objects. Moreover, they are localised near the surface and can be effectively scattered (reflected) by any objects on the ground surface or slightly below it. In this paper, some preliminary results of theoretical calculations of the scattering of Rayleigh waves by simple models of land mines are reported. The obtained results show that scattering of Rayleigh waves can be a viable method of land mine detection.
