UHF Radio Wave Attenuation Factor Distance Dependence Database

Description

Almost each sea-going vessel is known to be equipped with navigation, communication and other radio engineering facilities that serve to secure the safety of navigation and are chiefly operated at UHF-wave band. The key parameter of a propagation path is the (radio) wave attenuation factor and its distance dependence. A diversity of meteofactors influencing the radio signal attenuation over the oceanic expanses and the lack of experimental data could be routinely acquired were the compelling reasons to develop the attenuation factor distance dependence database.

Innovative Aspect and Main Advantages

The database allows solving the following problems:

  • to determine parameters of radar, navigational and another radio engineering systems developed to provide necessary coverage range in the World Ocean regions in question;
  • to make coverage range diagnosis and forecast for existing and exploited radar, navigational and another radio engineering systems in the World Ocean regions in question, which improve shipping safety;
  • to conduct continual monitoring of UHF wave propagation conditions in various regions of the World Ocean.

Areas of Application

The distance dependences of the attenuation factor for the UHF waves may find their practical use in designing and developing the radio engineering facilities that are capable to operate over oceanic surfaces and in validating the existing theoretical radio wave propagation models.

Stage of Development

The database of radio wave attenuation factor distance dependences for ranges in 20?600 km was developed on the base of experimental data obtained in different regions of the Atlantic, Indian, Arctic and Pacific Oceans. The database itself consists from a set of experimental data arrays, organized as a database, and of application program package, allows one to use this database and to solve rationally the problems in question. The database is ready for testing and demonstration.
