Abstract

An apparatus for detecting landmines is based on obtaining thermal signatures with an infrared camera (12) of a soil surface where a buried landmine might exist. An optical band filter (14) is positioned in front of the camera, which filter (14) is transmissive to selected band wavelengths but strongly attenuates radiation outside of the selected bands. The filter (14) is one selected to pass radiation in an optical band in which solar radiation is absent or highly attenuated at the earth's surface due to absorption by the molecular aerosol or particulate constitute of the atmosphere. This ensures that most of the solar radiation scattered from the ground surface is blocked from reaching the infrared camera's sensor, thereby eliminating clutter in infrared images of the soil surface.
