Abstract
The proliferation of objects in Earth's orbit has surged since the launch of the first artificial satellite in 1957, posing significant threats to space security, safety, and long-term sustainability. As of November 1, 2022, the US Space Surveillance Network (SSN) tracks over 22,000 objects, with more than 90% being rocket bodies and debris. However, this covers just around 5% of the risk posed by potentially damaging collisions [8]. The European Space Agency estimates that roughly 900,000 objects sized between 1 and 10 cm are currently untracked [13]. To address this growing challenge, it is imperative to develop ground-based radar systems capable of detecting and tracking resident LEO objects down to 2 cm in diameter.
For this reason, precise measurements are essential for extracting Keplerian elements used in orbit propagation
