摘要

The UK has conducted a number of studies into the requirements for Surveillance of Space and the associated analysis and dissemination issues which emerge that are needed to produce a Recognised Space Picture. The UK also has existing niche capability in a number of areas related to Surveillance of Space and potential in a number of other areas that could be harnessed for this purpose. For example, use of ground-based optical sensors, phased array radar technology, radar data processing for space object identification and development of small satellites, are all areas of expertise, which have current or potential applications for Surveillance of Space. The UK has operated a series of optical sensors for Deep Space Objects, using a number of distributed sites and optical sensors, based on COTS technologies of 10 years ago. A recent study has looked at the potential for an upgraded system using current COTS, improved processing and novel techniques. This essentially extends the remit to LEO as well as increasing the sensitivity of the system. In addition, some of the trends and technological capabilities that are emerging or have been demonstrated in radar research are summarised, and the relevant contribution to a system of complementary sensors discussed. Whilst such a system offers the potential to address many of the emerging requirements, some cannot easily be met with a ground-based system. The paper examines which of these cannot realistically be met with ground-based sensors and considers where the synergistic or complementary use of space-based sensors could be of use. As it is seen that operating in space becomes cheaper and technology matures, this becomes a more affordable and reliable option.
