Software Defined Radio (SDR) technology in combination with the computing power available in today's laptops and handheld computing devices has enabled the "smart radio". By adaptively combining multiple methods, operating across all seven layers of the OSI protocol stack, these SDR's can employ… More

DoD networks require increased digital bandwidth to wirelessly connected users, and is deploying a family of new software-defined radios (SDR) and networks called Joint Tactical Radio System (JTRS), based on the Software Communications Architecture (SCA). Current mobile ad hoc networking (MANET)… More

The SCA Technica team, with subcontractor General Dynamics C4 Systems and consultant Dr. Harvey Woodsum, propose to design and build a soldier-borne, small, lightweight, low power, LPI, wide band, quadrant and specific azimuth detector for GPS, combat net radio, and other jammers/emitters. We base… More

Homeland Security/First Responder networks require increased bandwidth and reliable connectivity. Future networks such as Project SAFECOM may deploy software-defined radios (SDR) compatible with Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). We leverage our SCA… More

DoD airborne networks require increased bandwidth to wirelessly connected users, and is deploying a family of software-defined radios (SDR) and networks called Joint Tactical Radio System (JTRS), based on Software Communications Architecture (SCA). JTRS waveforms can allow internetworking gateway… More

The DOD requires secure mobile ad-hoc networking (MANET) protocol stacks to satisfy operational requirements for the Joint Tactical Radio System (JTRS) family of SDR radios and networks, based on Software Communications Architecture (SCA). JTRS reference waveforms are being developed which allow… More

SPAWAR requires a high fidelity simulation of Radio Security Services (RSS) to enhance testing of Joint Tactical Radio System (JTRS) networking waveforms. Waveforms and enhancements are evaluated using a JTRS Surrogate Radio (JSR). We propose to modify a JSR through installation of radio security… More
