    • 2018 Beam-park observations of space debris with the EISCAT radars 

      Vierinen, Juha; Kastinen, D; Markkanen, Jussi; Grydeland, Tom; Kero, Johan; Horstmann, A.; Hesselbach, S.; Kebschull, C.; Røynestad, Elisabeth; Krag, Holger (Journal article; Tidsskriftartikkel, 2019)
      Monitoring the evolution of the space debris environment requires regular radar observations of the space debris population. This study presents the results from 24 hours of beam-park observations of space objects conducted simultaneously with the EISCAT Svalbard and Tromsø radars on and between January 4th and 5th, 2018. The measurements are processed with a new matched filter bank analysis program, ...

    • Next-generation Space Object Radar Tracking Simulator: SORTS++ 

      Kastinen, D; Vierinen, Juha; Kero, Johan; Hesselbach, S; Grydeland, Tom; Krag, Holger (Journal article; Tidsskriftartikkel, 2019)
      We describe the software toolbox SORTS++ which is the next-generation Space Object Radar Tracking Simulator (SORTS). This toolbox is able to simulate general Space Surveillance and Tracking (SST) applications from catalogue maintenance to cold-start performance for radar systems or collections of radar systems. We have applied this toolbox to the EISCAT 3D radar system, currently under construction, ...

    • USE OF EISCAT 3D FOR OBSERVATIONS OF SPACE DEBRIS 

      Vierinen, Juha; Markkanen, Jussi; Krag, Holger; Siminski, Jan; Mancas, Alexandru (Conference object; Konferansebidrag, 2017-06)
      We investigate the capabilities of the next generation ionospheric research radar EISCAT 3D (E3D) for observations of space objects. The radar is multi-static, and is therefore capable of observing instantaneous threedimensional vector velocity and position by observing round-trip delay and Doppler shift between the transmitter and three receiver sites. The radar is to be located in Northern ...
