This paper presents an overview on radar techniques for the observation of space debris in
low Earth orbits which were developed at FGAN in the frame of DARA and ESA/ESOC study …

Worldwide there is growing awareness of the hazard and long-term consequences of space
debris to space activities and astronomical research. Ground based radars and telescopes …

The steadily growing number of space debris objects poses a severe hazard to all kinds of
space operations. Especially the population of objects in the mid-size (1 to 10 cm) regime is …

The number of space objects monitored by USSPACECOM up to geostationary altitudes is
on the order of 10,000. These objects need to be larger than 10 to 30 cm in order to be …

Presently, there exists very little knowledge about the density and distribution of space
debris of the size of a few millimeters. The reason is that ground-based systems are not …

Space debris monitoring is nowadays a priority for worldwide space agencies, due to the
serious threat that these objects present. More and more efforts have been made to extend …

the Haystack radar and presents the results of measurements conducted between October …

Tens of thousands of debris are expected in the near future in the most critical Low Earth
Orbit regimes, hence representing a serious threat for European space assets. In the frame …
