The three-dimensional (3-D) imaging of objects buried in snow using multifrequency holography is discussed. It is pointed out that the cross-sectional images obtained by radar used for target detection in soils, sand, and snow do not meet expectations in identifying the shapes of targets. A 3-D imaging reconstruction technique using multifrequency holography is proposed that is applied to recognize the shapes of the objects buried in snow. An experimental system using X-band microwaves was constructed and image reconstruction was accomplished mathematically by computer, with the image displayed on a CRT using a specially designed circuit. Field trials are reported in which it was possible to obtain 3-D images of metallic cylinders and a mannequin buried in snow
