An Integrated Framework for Complex Radar System Design

Modern radar systems are complex and depend heavily on advanced signal processing algorithms to improve their detection performance. At the same time, the radio front-end must meet...

The provision of integrated modeling, simulation and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace...

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...

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

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated...

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

Measuring Radar Cross Section with Handheld VNAs

Radar cross section (RCS) is the measure of an object's ability to reflect radar signals in the direction of the radar receiver, i.e. it is the measure of the ratio of backscatter per...

Analysis of Clustering Tools for Moving Target Indication

Current and future forces operating in urban environments need the capability to detect slow-moving personnel inside buildings. To accomplish this, a time-domain approach was developed that uses a low-frequency, ultra-wideband (UWB) radar with a transmit pulse capable of penetrating...

Fiber-optic networks have benefited from nearly 20 years of continuous expansion (notwithstanding the brief, yet surprisingly quiet period from 2002 to 2005). For terrestrial networking,...

The two-transmission method is an improved method of determining, from microwave measurements, the complex permeability and complex permittivity of a sample of a material typified...
