Remote Sensing of Electromagnetically Penetrable Objects: Landmine and IED Detection
The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to identify these hazards, increasingly low dielectric contrast between newer, sophisticated landmines, and complex surrounding soil geometric in-homogeneities acts as an increasingly major impediment to successful detection. The present study investigates the use of the Finite Element Method in the COMSOL Multiphysics® software to model the propagation of electromagnetic waves introduced into the computational domain non-invasively. Four quantities of interest were investigated and analyzed numerically: depth, size, soil moisture, and frequency of incident waves, and the template generated by this research can be used to determine vital feedback about buried IEDs to perform a more informed and successful demining process.
