Covariance and Uncertainty Realism in Space Surveillance and Tracking

Characterizing uncertainty in estimating the state of a resident space object is one of the fundamentals of many space surveillance tasks.

Pulse Analysis Techniques for Radar and Electronic Warfare

Pulsed signals are widespread in radar and other electronic warfare (EW) applications, and they must be accurately measured for manufacturing, design of countermeasures, and threat...

Angular Random Walk Estimation of a Time-Domain Switching Micromachined Gyroscope

The primary metrics that prohibit the use of microelectromechanical systems (MEMS) gyroscopes for navigation-grade inertial navigation units (IMUs) are angle...

Using High Bandwidth Oscilloscopes to Analyze Radar and Electronic Warfare Systems

Whether for multi-channel analysis, or for wider analysis bandwidth in a measurement, high bandwidth oscilloscopes offer an alternative to traditional...

DPA Countermeasures — Theory vs. Practice

The Threat

In today’s interconnected world, the information that we generate, store, transmit, and receive has become a valuable commodity. We have increasingly turned to cryptography as a tool...

A Hardware-Centric Approach to Countering Side-Channel Threats

From laptops and mobile devices to cars and airplanes, we are seeing near-daily threats to the systems and devices we use. Systems being used and deployed in the aerospace and...

Big Data, Aircraft, and a Better Future

The hype phrase today is “Big Data.” It is a phrase Mark Bünger, Research Director for Lux Research, believes can have a number of definitions depending on who is doing the defining. Bünger was...

Developing and Validating Statistical Cyber Defenses

Enterprise business processes are more connected than ever before, driven by the ability to share the right information with the right partners at the right time. While this...

Characterization of Ceramic Composite Materials Using Terahertz Nondestructive Evaluation Techniques

This work describes the use of nondestructive evaluation (NDE) techniques to characterize defects such as rust, voids, etc. in materials,...

Thermal-to-Visible Face Recognition

For nighttime surveillance, acquisition of visible light imagery is impractical due to the lack of illumination. Thermal imaging, which acquires mid-wave infrared or long-wave infrared radiation naturally...

Implementing On-Board Cloud Detection on a Reconfigurable Computer

Reconfigurable Computers (RCs) combine traditional microprocessors with field programmable gate arrays (FPGAs), and are characterized by lower form/wrap factors compared to...

Developing Condition-Based Maintenance

Like any manufacturing equipment, semiconductor fabrication systems have a finite lifetime. Technicians normally perform maintenance on these hardware systems according to preset schedules and...
