An inflatable shield for suppressing the characteristic radiation signature of a satellite is described. The shield is conical-shaped and made from a thin synthetic polymer film material coated with a radiation reflecting material, such as gold or aluminum. At least one subliming agent is contained within the shield to inflate the shield when exposed to heat. An ultraviolet curable slurry coats the inner walls of the shield and permanently hardens the shield upon exposure to ultraviolet radiation from a self-contained source. The shield optionally may include absorbing and desiccant agents to absorb unwanted gas and water and prevent interference with the primary mission of the satellite. Additional means may be included for moving and positioning the shield with respect to the satellite. |

DETAILED DESCRIPTION In order for camouflage to be effective, the target must blend in with the background by incorporating similar visible, laser, radar, and infrared signatures.
On earth, such backgrounds typically include woodlands, deserts, or arctic tundra.
As indicated above, the typical background of a satellite is the void of outer space.
Using absorbing or non-conducting materials as camouflage for a satellite would be useful for protection against radar to some extend; however, it would not offer much protection from active laser tracking systems.
Nor would it be useful as visible and infrared radiation signature suppression.
It is an object of this invention to provide a satellite signature suppression shield which is effective against active and passive detection systems.
Examples of active tracking systems include radar and laser tracking systems; examples of passive detection systems include infrared and visible radiation detection systems.
It is another object of this invention to provide a satellite signature suppression shield which utilizes reflective surfaces to reflect radiation away from the satellite and away from the tracking sensors.
It is a further objective of this invention to provide a satellite signature suppression shield which is movable with respect to the satellite, such that the shield may be oriented in the direction of the threat.
It is another object of this invention to provide an inflatable satellite signature suppression shield which is inflated and rigidized at a remote location.
These and other advantageous aspects of this invention may be realized by providing an airtight conical-shaped inflatable shield wherein at least one subliming material is included.
The shield further includes rigidizing agents, and optionally absorbing agents and desiccant materials.
