Orbits are an invaluable resource for the global community. However, space
pollution is becoming more pronounced as the accumulation of debris continues.
Deliberate collisions are a relevant source contributing to this development.
When Microsat-R was destroyed with a missile in 2019, it ejected numerous
fragments into orbit. Based on observations made with EISCAT UHF, this thesis
will investigate the evolution of this debris cloud. This is achieved using the
results from four different measurement campaigns from 2018 to 2021.
