Image compression is an important component in modern imaging systems as the size of the raw data collected is getting larger. For example, a commercial Wide Area Motion Imagery (WAMI) image data size is over 144 Megapixels (12,000 × 12,000 pixels), and the next generation WAMI image data size will be at the level of 1.6 Giga-pixels (40,000 × 40,000 pixels). The large file size transmission is limiting...
With the rapid development of sensor technology, multiple sensors are often available in many engineering applications, such as space object tracking. How to effectively use multiple sensor information is the key to achieving accurate space object state information. In this paper, the information weighted consensus (IWC) strategy is deployed to solve the cooperative sensor tracking problem. In addition,...
In this paper, a pursuit-evasion (PE) orbital game approach for space situational awareness (SSA) is presented to deal with imperfect measurements and information with uncertainties. The objective function includes the distance to be minimized by pursuers (observers/sensors) and maximized by evaders (space objects being tracked). The proposed PE approach provides a method to solve the realistic SSA...
Accurate and timely space object tracking is important for space surveillance missions. Among various sensors such as ground-based radars, a space-based visible (SBV) sensor has been considered as an important sensing technology to achieve the stringent goals of space surveillance due to its high-accuracy angle measurements, faster observation rates, and large sensing coverage. To achieve certain...
