17. The electrical character of surface material, as indicated by its complex dielectric constant, is also critical in the interpretation of radar images.

Radar reflectivity is considerably increased in the presence of water, which has a dielectric constant greater than 10 times that of dry materials.

(i) To endeavor to develop advanced mine detection technology and equipment (such as non metallic mine detectors and detectors adopting the working principle of infrared thermovision or soil dielectric coefficient), so to improve the efficiency of detecting MOTAPM through various ways and means.
