Formulation of the problem. A quantitative assessment of the field properties during tropospheric propagation of VHF radio waves is |
|
|
based on the results of processing experimental data, since information on the statistical characteristics of weak dielectric permittivity |
|
|
inhomogeneities does not give such an estimate [1]. Obtaining dependencies for statistical distributions of the propagation range of |
|
|
radio waves of this range and a number of their estimates have theoretical and practical significance in the construction of systems of |
|
|
stationary receiving stations. |

Results. A statistical distribution of the probability of realizing the maximum line-of-sight range for a VHF communication channel was obtained, taking into account tropospheric refraction, the concept of the intensity of its implementation was introduced, which made it possible to determine the potential that gives an estimate of the probability of the existence of a communication channel for a system of several receivers located in space. |
|
Practical significance. The obtained ratios and estimates will make it possible to justify decisions on the placement of a system of stationary receiving stations with a guaranteed probability of providing a communication channel.
