Abstract:

This study was performed to determine the feasibility of multiple-use mobile andor transportable ground tracking terminals for relay of communications data by microwave LOS or tropospheric scatter techniques as well as in relay networks where interface with synchronous satellites or RPVs is required. Attention is given to projected developments in solid-state RF power generation, low-noise electronics, signal processingmodemsmultiplexing, and to terminal type, size weight and costs. A family of ground terminals is postulated to satisfy the varying needs of tactical trunk users. Modularity in power amplifiers, antennas, and multiplex interfaces is considered. Key study results indicate that a TDMA-spread-spectrum system could operate with RPVs and the synchronous satellite. Preferred frequencies are X-band for the RPVs and satellites wherein total theatre data requirements of 42 or 110 Mbps can be readily handled with 8 terminals and satellite beamwidths of less than 1.50. The preferred millimeter system is at 94 GHz using 4 terminals, multibeam 0.05 deg satellite patterns, and 2-3 watts of satellite power per beam.
