Space Surveillance with High-Frequency Radar

open access: yesSensors
High-Frequency (HF) radar is well suited to the surveillance of low-earth-orbit space. For large targets, a small deployable HF radar is able to match the detection performance of much larger space surveillance radar systems operating at higher frequencies.

Processing of Space Surveillance Observations

open access: yes, 2021
This thesis covers the processing of different types of space surveillance measurements. The emphasis is on the initial build-up of a catalogue. Most experiments focus on the identification of objects from pairs of observations by testing whether these two observations could originate from the same object.

Orbit Determination for Space Surveillance

open access: yes, 2016
This thesis presents the assessment of candidates for orbit determination (OD) within the realtime simulation SpaceView & Analyst, developed at Fraunhofer FHR. The goal of this simulationis to investigate future scenarios for space surveillance, which implies the continuous monitoring of objects in space. This is necessary because most objects in space

Simulation of space-based visible surveillance images for space surveillance

SPIE Proceedings, 2011
The simulation of space-based visible surveillance images can offer technical support to the index argumentation, scheme design and ground-tests of spatial optical system. Based on the analysis of the space-based visible surveillance principle, this paper establishes the simulation framework of space-based visible surveillance images, as well as its

Privacy in video surveilled spaces

Journal of Computer Security, 2008
We present a system prototype for self-determination and privacy enhancement in video surveilled areas by integrating computer vision and cryptographic techniques into networked building automation systems. This paper describes a system prototype and research work that has been conducted by an interdisciplinary team of researchers.
