    Description

    The Department of Defense, specifically the U.S. Army Command, Control, Communications, Computer, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Center, is seeking industry input through a Request for Information (RFI) for Software Defined Antenna (SDA) technologies. The primary objective is to identify solutions that enable tactical radios to transmit flexibly across the Electromagnetic Spectrum (EMS) to mitigate issues of congestion and contention, particularly in tactical vehicles that currently rely on omnidirectional antennas, which pose high physical and electromagnetic signatures. The Army is looking for multi-band SDAs with advanced frequency sensing capabilities that can automatically adjust legacy radio frequencies, supporting a wide frequency range (700 MHz - 6 GHz Threshold, 30 MHz - 6 GHz Objective) and various radio types and waveforms. Interested parties are invited to submit whitepapers detailing their proposed solutions, including performance metrics and Technology Readiness Levels (TRL), by September 2, 2025. For further inquiries, contact the Technical POC at usarmy.apg.devcom-c5isr.mbx.esi-bus-ops-acq-baa@army.mil.

    DRAS-25-2814-0-Software Defined Antenna RFI Draft (10 JUL).pdf
    The US Army C5ISR Center has issued a Request for Information (RFI) for Software Defined Antenna (SDA) technologies. This RFI aims to identify industry solutions that enable tactical radios to transmit across the Electromagnetic Spectrum (EMS) to avoid congestion and contention. The current challenge involves tactical vehicles using omnidirectional antennas, which create high physical and electromagnetic signatures, making them vulnerable. The Army seeks multi-band SDAs with frequency sensing capabilities to automatically adjust legacy radio frequencies. Key requirements for the SDA include supporting a wide frequency range (700 MHz - 6 GHz Threshold, 30 MHz - 6 GHz Objective), real-time RF spectrum sensing and automatic frequency switching, and compatibility with various radio types and waveforms. The RFI also requests information on the antenna's physical characteristics, such as size, weight, power, and cost (SWaP-C), and its ability to support MIMO radio systems and MANET networks. Whitepapers detailing proposed solutions, including performance contracts, measures of effectiveness, delivery models, and Technology Readiness Levels (TRL), are due by September 2, 2025.
