JTRS-an open, distributed-object computing software radio architecture

The Joint Tactical Radio System (JTRS) program is a 3-step process to define, standardize, and implement a software defined radio architecture. Step 1 resulted in a baseline architecture definition. In Step 2 the architecture definition will be developed and validated as the Software Communications Architecture (SCA) which will be the basis for future DoD software radios. The SCA is also expected to become the standard for Government and commercial software radios. Step 3 activities will result in procurement and integration of systems and waveforms that are compliant with the SCA and which satisfy individual DoD user requirements. During Step 3, the architecture will continue to evolve in response to new or changing warfighter requirements and technology advancements. The JTRS is defined in terms of its hardware, software, networking, and security architecture. This paper addresses the Software Communications Architecture.
