Evaluation of microwave sensors for landmine detection

Landmines and improvised explosive devices (IED) continue to be a leading cause of death and injury to civilians and military personnel abroad. The detection and removal of these devices before detonation is necessary to improve safety. This work proposes the use of microwave radiometry for long-range monitoring and microwave coplanar sensors for short-range monitoring. The sharp contrast between the thermal and electrical properties of IEDs and the surrounding medium (soil and air) can be utilized to detect their presence. The feasibility of using planar transmission lines as landmine and IED detectors is explored. This will create a safe environment for the indigenous population and security personnel overseas.
