    • 6-meter wavelength polarimetric inverse synthetic aperture radar mapping of the Moon 

      Tveito, Torbjørn (Master thesis; Mastergradsoppgave, 2019-06-01)
      Remote sensing of planetary surfaces is an effective method for gaining knowledge of the processes that shape the planetary bodies in our solar system. This is useful for uncovering the environment of the primordial solar system and to study the current state of the upper crusts of the other planets in our neighborhood. A recent 6-meter wavelength polarimetric radar map of the Moon showed unexpectedly ...

    • Investigation of exceptionally radar-dark regions on the lunar nearside 

      Tveito, Torbjørn; Vierinen, Juha; Serrano, Alessandra (Conference object; Konferansebidrag, 2019-08)

    • Lightboard – a new teaching tool at the Faculty of Science and Technology at UiT 

      Malyutina, Elena; Gustavsson, Björn Johan; Vierinen, Juha; Tveito, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-05)
      We would like to present a new tool that was built by three lecturers at UiT last semester – Lightboard. This tool was used before in other countries and other universities, but never at UiT. The COVID-19 pandemic situation motivated the lecturers to find a way to do online lectures differently. Blackboard and chalk work well for natural sciences as long as the lecture is physical and the teacher ...

    • Planetary radar science case for EISCAT 3D 

      Tveito, Torbjørn; Vierinen, Juha; Gustavsson, Björn Johan; Narayanan, Viswanathan Lakshmi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)
      Ground-based inverse synthetic aperture radar is a tool that can provide insights into the early history and formative processes of planetary bodies in the inner solar system. This information is gathered by measuring the scattering matrix of the target body, providing composite information about the physical structure and chemical makeup of its surface and subsurface down to the penetration ...

    • Radar observability of near-Earth objects using EISCAT 3D 

      Kastinen, Daniel; Tveito, Torbjørn; Vierinen, Juha; Granvik, Mikael (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)
      Radar observations can be used to obtain accurate orbital elements for near-Earth objects (NEOs) as a result of the very accurate range and range rate measureables. These observations allow the prediction of NEO orbits further into the future and also provide more information about the properties of the NEO population. This study evaluates the observability of NEOs with the EISCAT 3D 233 MHz 5 MW ...
