Microwave and Scatter Communications System for the Eglin Gulf Testing Range

A seven-hop 295-mile combined microwave and tropospheric forward-scatter communications system is being installed for carrying voice, timing, telemetering, radar data, and controls for the Eglin Gulf Testing Range. System design of the frequency-diversity 7000-mc microwave system is reviewed, as well as the design of the four-fold diversity 2000-mc scatter system. Problems of special interest on transmission of timing signals, telemetry, and radar digital data are discussed and solutions indicated. Considerations for reliability, flexibility and ease of maintenance are indicated. Integration of the range operations by use of the commnnications system is described.
