Introduction
• Military communications objectives are complex and
dynamic
• Communications need to adapt to changing needs
• “Software Defined Radio” evolved to meet this challenge
• This presentation will provide an overview of a typical
military radio product followed by a hands-on
demonstration of a Harris radio communications system

Software Defined Radio
Modern military radios are essentially
software processes and applications
running on specialized computing
platforms

SDR Advantages
• Elimination of analog hardware and associated cost
• Simplification of radio architectures and improved performance
• Hardware specific components are replaced by DSPs and
FPGAs
• A family of radio “products” can be implemented using a
common platform architecture
• New products can be more quickly introduced into the market.
• A common radio platform for multiple markets significantly
reduces logistical support and operating expenditures
• Software can be reused across radio "products”
• Can reduce development time and cost dramatically
• Allows "bug fixes" to be installed in the field
• New features and capabilities can be added without
significant cost
• Software can compensate for problems in other areas of
the system.
• Ability to receive and transmit various waveforms using
common hardware
• Important for coalition interoperability
