Abstract

We propose to develop and thoroughly test a stand-off detection system for the identification and location of metallic and non-metallic land mines using a sensor fusion/data fusion system. The system proposed for development employs seismic and radar wave fields and phased array signal recording and processing for imaging of buried objects using reflected wave fields. The critical component of this system is the real-time processing of the sensor data by previously developed Array Beam Imaging (ABI) methods. The Phase I research effort provided demonstrations of the feasibility of the proposed system, in that seismic generation, propagation, and detection results were found to be favorable for imaging and high quality radar images of buried mines were produced during field tests. The expected outcome of the proposed Phase II work will be the development of a portable, hand deployable, stand-off system which will accurately locate, identify, and display tomographic images of buried targets in a survey area. A prototype system will be designed to produce high-resolution, three dimensional images and tomographic section of reflectors with images of shape and internal structure used for rapid identification of mines in cluttered environments. This dual-field detection system will be fabricated and tested during the proposed development program to optimize the system for practical field use. Direct benefits from a successful Phase II program would be the development of a workable mine imaging system that will allow the commercial production of land mine detection systems in Phase III. Therefore we expect to develop an imaging system as a commercial product for deployment by DOD, as well as by international agencies for humanitarian demining. Phase II results would also be used in on-going development of geophysical exploration systems, engineering systems for non-destructive testing and environment hazards evaluation systems.
