Abstract
ABSTRACT Several mine detection systems are currently under development which will provide airborne mine detection capabilities.For example, the COBRA program utilizes a multispectral video camera which will provide an interim, clear weather,daylight capability when deployed in a Pioneer unmanned aerial vehicle (UAV). The ASTAMIDS program has a dualapproach, one contains an active polarized source as well as a passive JR camera and the other only a passive JR imager.Either ASTAMJDS system will provide day/night and limited visibility operation. The use of a PMMW Imaging sensor promises to provide day/night and all weather mine detection performance. Attenuation in the MMW regime is not dramatically effected by adverse weather. Jn addition there is a large contrast between metal targets and the background forair to ground scenarios. Furthermore, due to the long wavelengths, vegetation and soils are not completely opaque in theMMW regime, offering the possibility to detect buried targets under specific conditions. This paper will describe theassessment of an imaging PMMW sensor for mine detection. The results of data collection and modeling analysis will bepresented as evidence to the utility and capabilities of the technology to perform under adverse weather conditions.Keywords: passive millimeter wave, imaging, technology assessment1. INTRODUCTIONThis manuscript will document the feasibility assessment of a Passive Millimeter Wave (PMMW) system for standoffairborne minefield detection performed for the Coastal Systems Station, Dahigren Division, Naval Surface Warfare Centerunder U.S. Marine Corps sponsorship. The feasibility assessment consisted of a technology survey, data collection, signatureanalysis, and synthetic image generation. The technology survey provides an assessment of the state of the art in millimeterwave (MMW) components and imaging systems. Data was collected of mines under various conditions to demonstrate the
