Array Beam Imaging for High Resolution Stand-Off Mine Detection
Abstract
Array Beam Imaging (ABI) software has been developed and tested using both radar and seismic wave fields for imaging based on backscattered (reflected) wave pulses from target objects. The ABI software is designed to produce high resolution target images showing internal structure of reflecting objects as well as external surface features. The images obtained are quantitatively proportional to the reflectivity (impedance contrasts) at target surfaces that produce reflections of incident waves. Therefore, reflectivity images using seismic and electromagnetic waves produce sets of images that measure quite different physical properties of the targets. These independent images can be compared (correlated) with the corresponding images of standard mine types for identification purposes using external and internal boundary shapes and other special reflectivity differences between mines and miscellaneous clutter. This report covers the period of the extended Phase 1 study, which includes the interim funding period prior to Phase 2.
