3D imaging of Earth’s surface layers (such as canopy, sub-surface, or ice) requires not just the penetration of radar signal into the medium, but also the ability to discriminate multiple scatterers within a slant-range and azimuth resolution cell.

An ultra-wide-band (UWB) multiple-input multiple-output (MIMO) radar with a sparse array is designed and manufactured for three-dimensional near-field imaging applications such as concealed weapon detection. Contrary to existing mmW imaging radars, U

We study whether the birthplaces of sunspots (defined as the location of first appearance in the photosphere) are related to the planetary tides on the Sun. The heliocentric longitudes of newly emerging sunspots are statistically compared to the long

In recent years, all-sky camera airglow observations of evolving nighttime F-region structures have raised questions regarding the formation and apparent motion of these often wave-like structures. We address these issues using a pseudo-spectral meth

For successful beam shaping and scanning in phased array radars, it is essential to precisely set the amplitude and phase of each element channel. However, considerable amplitude and phase differences among the channels can occur due to the different

We combine all-sky images of 630 nm airglow with the 3D structure of electron densities in the F-region above Arecibo. The line-of-sight electron densities obtained from the two azimuth-scanning beams of Arecibo incoherent scatter radar (ISR) are plo
