Design Patterns of the JTRS Infrastructure

The concept of the Joint Tactical Radio System (JTRS) infrastructure is to define a radio host environment for the execution of waveforms and applications. Software developers are guaranteed a specific set of real time operating functions, distributed messaging through Common Object Request Broker Architecture (CORBA), and radio domain-specific interfaces such as Global Positioning System (GPS), Ethernet, audio, etc. This promotes reuse and portability of waveform components. The hardware dependencies are isolated from the applications by the Application Program Interfaces (APIs) defined for radio devices. Software design patterns have been developed by the JTRS community to define a scaleable and extensible infrastructure. Aggregation, least privilege, extension, explicit enumeration, and deprecation enable the infrastructure to support varying missions and form factors. These design patterns permit the instantiation of a radio infrastructure suitable for the platform footprint and resources of a single-channel handheld radio, yet also permit it to be scaleable and extensible to the requirements of a multiple-channel wireless networking gateway.
