The RATS Radio Traffic Collection System
|Kevin Walker and Stephanie Strassel|
The DARPA RATS Program focuses on the development of new technologies for identifying and processing speaker-tospeaker communications over degraded radio channels. In order to build a corpus to address this research question, we developed a system that takes a clean source signal and transmits it over eight different radio channels, where the variation from channel to channel results in a range of degradation modes. Each channel included in the collection system has unique characteristics targeting different modulation types, different carrier channel bandwidths, and different operating bands.
