This project will develop techniques for processing sequences of images of a space object, taken from ground-based telescopes, to create a three dimensional model of the object and to calculate the object's attitude motion as a function time. This Shape from Motion problem has been studied since the… More

Stellar Science has developed innovative techniques for the automated processing of sequences of images into three dimensional models in near real time, and demonstrated those techniques on space surveillance imagery. Using feasibility studies that rigorously characterize the performance of several… More

We propose to develop an algorithm capable of autonomously converting standard 2D space surveillance imagery sequences into 3D stereo movies. We will extend and integrate our existing algorithms, which have already been demonstrated to handle space surveillance data, to build a system that requires… More

Stellar Science has developed innovative techniques capable of autonomously converting standard 2D image sequences into 3D stereo movies, and has successfully tested these techniques on a wide variety of space surveillance imagery. Our algorithm first solves for the satellite's shape and motion… More

Computer-aided design (CAD) modelers and signature simulation experts often must use multiple formats and types of geometric models representing the same object in order to support different applications. In the signature analysis domain, radar simulation generally requires faceted models, whereas… More

Accurate geometric and mathematical modeling of three-dimensional object shapes is a critical component of a variety of applications, ranging from design and manufacturing, to modeling and simulation. The models used in these applications may be created using interactive Computer Aided Design (CAD)… More

To reduce the cost of new hardware development, the Missile Defense Agency (MDA) is developing fast new computational tools that enable in-the-loop hardware testing. The MDA and contractors have developed high-fidelity scene modeling tools such as the Fast Line-of-sight Imagery for Target and… More

ABSTRACT: To reduce the risk of on-orbit collisions, the Joint Space Operations Center (JSpOC) tracks objects in its Space Catalog and forecasts potential conjunctions. Because both the size of the Space Catalog and its ephemeris update frequency are expected to grow significantly in the near term,… More

ABSTRACT: RF transmitting devices are found nearly everywhere today, ranging from lower-power cell phones to radar equipment to high-energy weapons systems. Accidental exposure of humans to the RF radiation emanating from these devices can cause harmful thermal effects including tissue damage or… More
