Commercial Test and Measurement equipment has advanced greatly with the emergence of sophisticated cellular and wireless local area network technology and can be used to intercept, analyze and exploit our military communications signals.
Information, or ‘content’, on the World Wide Web is replicated and distributed across the world to ensure high availability to the end-user. User expectations for rapid access to content have led to the creation of content distribution systems that enhance the user experience. Consequently, users may quickly access content used for everyday living, from restaurant menus and maps, to local and world news.
Dominance of the radio frequency (RF) spectrum is critical to successful U.S. military operations. Today, we do this using discrete radar, electronic warfare (EW), and communication payloads that are separately designed, procured, and integrated on platforms. These payloads typically use dedicated apertures, are realized with tightly coupled hardware and software, and are not well-coordinated in their use of spectrum.
The Direct On-Chip Digital Optical Synthesizer (DODOS) program seeks to create a technological revolution in optical frequency control analogous to the disruptive advances in microwave frequency control in the 1940s. That early development ushered in a new era for microwave technology, transformed modern warfare, and has since been enabling a multitude of Department of Defense (DoD) and civilian capabilities, including radar, navigation technologies, and satellite and terrestrial communications. Extending frequency control to the optical regime is anticipated to greatly extend the technology base for the next generation of warfighter and other capabilities.
The Dynamic Network Adaptation for Mission Optimization (DyNAMO) program is developing and testing technologies that enable adaptive, mission-responsive networking among diverse platforms in contested environments.
