Detecting space objects with Earth-observation radar satellites
Juha Vierinen, Laura-Kristin Scholtz, Ulrik Noer +3
Millimetre-to-centimetre orbital debris poses a hazard to spacecraft, but its abundance remains difficult to measure. Spaceborne radars offer a substantial sensitivity advantage at…
Radar and Infrasound Observations of the 2026 May 30 Cape Cod Bay Superbolide
Juha Vierinen, Ryan Volz, Marc Fries +10
Metre-scale impactors connect near-Earth-object dynamics, atmospheric-entry physics and meteorite delivery, but their pre-impact orbits and material properties are rarely measured…
The PANSY Meteor Head-echo Orbit Catalogue: Continuous Antarctic Radar Observations of Southern Meteoroid Streams
Juha Vierinen, Jorge L. Chau, Koji Nishimura +7
Meteor head echoes from high-power, large-aperture radars provide pulse-resolved positions and velocities for individual micrometeoroids in a submillimeter-radius range that contri…
GPGPU Acceleration of Incoherent Scatter Radar Plasma Line Analysis
Natalie Hilliard, Juha Vierinen, Philip J. Erickson
The incoherent scatter radar (ISR) technique is a powerful remote sensing tool for ionosphere and thermosphere dynamics in the near-Earth space environment. Weak ISR scatter from n…
