The performance of passive microwave radiometers in detecting buried landmines is adversely affected by the presence of foreign objects and moisture in the soil. One possible way to increase the signal contrast between the mine and the surrounding soil is to make the soil artificially dry by reducing the moisture to its solid state. This can be accomplished by injecting liquid nitrogen into the top layers of the soil. This paper describes preliminary result of an experiment designed to test this approach under controlled laboratory conditions.
