A New Remote-Sensing Method for Mine Detection using HPM Irradiation and IR Detection.
Abstract
A remote-sensing method based on active high-power microwave (HPM) illumination and detection in the infrared (IR) region is described for the detection of shallow buried landmines. This method is based on different interactions of the incident HPM radiation with the mine and the surrounding soil which occur due to a difference in their complex dielectric constants. This leads to the development of a thermal signature of the mine at the soil surface that can be detected in the infrared region. The thermal signature which is observed initially in near real-time persists for several minutes following HPM illumination. It is primarily made up of two components. The first component appears on the soil surface in near real-time due to the interference of the incident HPM beam and the HPM beam reflected by the mine. A second signature is due to the absorption of microwave energy by the mine. This signature appears at the soil surface alter a brief time-delay from the start of HPM illumination. At any instant, the resultant thermal signature at the soil surface is the sum of the two time-dependent signatures. In this report we provide both laboratory and field trial results obtained using this method to detect metallic and non-metallic mine surrogates, dummy mines without explosives and live mines with explosives but without any fuse.
