Hyper-Spectral Speckle Imaging for Space Situational Awareness

چکیده
Abstract When observing targets in the near-Earth space environment using ground-based telescopes, Earth’s turbulent atmosphere and telescope’s aperture combine to act as a low-resolution spectrometer. The light at disparate wavelengths from given point object lands different spatial locations focal plane. Here we investigate feasibility of capitalizing on this effect provide snapshot hyper-spectral imaging through ultra-broadband speckle imaging. In particular, focus potential for images high-resolution, high-contrast closely spaced objects with large contrast brightness. It was found that technique is capable distinguishing down 0.14 arc-seconds providing estimates spectra. primary component had very good recovery, while secondary’s recovery dependent separation ratio.

Wideband Hyperspectral Imaging for Space Situational Awareness
Wideband hyperspectral imaging (WHSI) systems simultaneously collect spectral and spatial imagery across a broad spectrum that includes the visible/near infrared (VNIR), short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) regimes. These passive optical systems capture reflected sunlight and thermal emissions from targets enabling the characterization of surface m...

The three-dimensional imaging of satellites from a groundbased radar is considered in a space situational awareness context. Utilizing the synthetic aperture radar (SAR) tomographic formulation and a model of the collection geometry in a specific low Earth orbit scenario, the shape and repeat nature of collection passes from ascending and descending orbits is evaluated and constraints on the fo...

United States defense operations are greatly enhanced by satellites, however these key assets are vulnerable to perils such as space weather or acts of aggression. Unfortunately it is not only difficult to defend against such threats, it can be difficult to determine the cause from the ground. What may at first appear to be a routine system glitch may in fact be something much more serious. Thi...
متن کاملFAWKES Information Management for Space Situational Awareness
Current space situational awareness assets can be fully utilized by managing their inputs and outputs in real time. Ideally, sensors are tasked to perform specific functions to maximize their effectiveness. Many sensors are capable of collecting more data than is needed for a particular purpose, leading to the potential to enhance a sensor’s utilization by allowing it to be re-tasked in real ti...
