The experimental results of investigation of the total cross — section of scattering and absorption (extinction cross — section) σt of stalks and strip leaves of grass in millimeter waves range are presented. The investigation was carried out us
In this paper, millimeter-wave imaging of foreign object debris (FOD)-type objects on the ground is studied with the help of ground-based synthetic aperture radar (GB-SAR) technique. To test the feasibility of detecting runway FODs with this techniqu

A Study On Millimeter-Wave Imaging Of Concealed Objects: Application Using Back-Projection Algorithm
Millimeter-wave (MMW) imaging is a powerful tool for the detection of objects concealed under clothing. Several factors including difierent kinds of objects, variety of covering materials and their thickness, accurate imaging of near-fleld scattered
