DOI: 10.1109/tthz.2017.2781462
Abstract: Based on the assumption of isotropic scattering, a wider angle aperture can provide improved resolution of synthetic aperture radar images. However, due to the limited angular persistence of scatterers for high-resolution terahertz radar, traditional imaging… read more here.
