2026.04.22 - N. Alvarez (NASA JPL) Bistatic Radar Observations of Artemis II

Описание: Abstract: This presentation summarizes bistatic radar observations of Artemis II (Integrity) conducted using DSS-13 and the Green Bank Telescope. The campaign consisted of five tracking passes distributed along the Artemis II trajectory, covering a range of geometries and operational conditions. Across these tracks, a comprehensive dataset was collected, including continuous wave (CW) and modulated waveforms (binary phase-coded and chirp), enabling the extraction of Doppler observables and signal characterization over time. The results presented here showcase the application of an existing bistatic radar capability to spacecraft tracking, highlighting data quality, consistency across tracks, and performance under varying observation conditions.
