AbstractOne of several methods currently under investigation to increase telemetry efficiency is channel diversity selection. A spatial technique we are exploring exploits a signal quality indicator of phase demodulation to select ‘competing’ telemetry channels sourced by antenna separated by fractional wavelengths. The Advanced Range Telemetry (ARTM) program, a Centralized Test and Evaluation Improvement Program (CTEIP) research project funded by the Office of the Secretary of Defense (OSD), recently investigated three switching criteria for a multiple antenna system. This paper will discuss an algorithm that controls channel selection, or diversity branch selection (DBS), using a combination of the techniques investigated.
