A Study of Tactical Communications Problems

摘要

The study involved three technical problems. Air transportable tactical communications subsystems that comply with pertinent security standards: Communications requirements were investigated and an overall communications plan presented which is compatible with existing and future tactical communications systems. This study shows that the alternate routed communications system plan is feasible and two communications vans at both the main field and the satellite field are desirable. Short range communications for air traffic control: ATC voice coordinated circuits will be required between multiple base complexes and neither line of sight VHF nor HF/SSB is suitable. Communications requirements were established. Investigation of LF-MF and UHF/SHF troposcatter for short and intermediate ranges were accomplished. Results indicate that tropospheric scatter is most reliable for ranges of 15 to 200 miles and HF for ranges in excess of 200 miles. Specifications of a tactical HF directional antenna: Current log monopole antennas are bulky and require too much set up time. Results indicate three approaches can alleviate the bulk, weight, erection problems. Inductive loading techniques. Purchase of off-the-shelf hardware. Development of state-of-the-art designs. (Author)
