The space environment has become highly congested due to the increasing space debris,
seriously threatening the safety of orbiting spacecraft. Space-based situational awareness …

The rapidly growing number of space activities is generating numerous space debris, which
greatly threatens the safety of space operations. Therefore, space-based space debris …

A catalogue of over 22,000 objects in Earth's orbit is currently maintained, and that number
is expected to double within the next decade. Novel data collection regimes are needed to …

A traditional tip-tilt mirror control system with an image loop is used to effectively reject
structural vibrations in optical telescopes. However, its bandwidth is restricted by low …

Abstract Space debris detection, as space environments become increasingly crowded, has
gradually become a field in urgent need of research. Due to the dim and undersized …

Continuous orthogonal moments are widely used in various image techniques due to their
simplicity and good rotational invariance and stability. In recent years, numerous excellent …

Conducting surveillance of the geocenric orbits is a key task towards achieving space
situational awareness (SSA). Our work focuses on the optical detection of man-made objects …

Abstract The Low Earth Orbit (LEO) region is populated by tens of thousands of objects,
which include not only active satellites, but also space debris which can pose a real danger …

The low-Earth orbit (LEO) is filled with active satellites, but also with space debris, which
need constant observation. The orbiting objects may be affected by collisions or by …

The detection of dim and small space-targets is crucial in space situational awareness
missions; however, low signal-to-noise ratio (SNR) targets and complex backgrounds pose …
