In article it is considered questions of an estimation of influence of stochasticity of parameters of a line of distribution of the radiowaves defining possible errors of phase measurements and, as consequence, uncertainty of spatial position of front of an electromagnetic wave, on accuracy one-item phase of coordinates definition, focused on formation of estimations of a site of a source of a radio emission on curvature of front of a wave. In interests of carrying out mentioned above estimations on the basis of a method of statistical tests the imitating model of process of definition of coordinates in the conditions of spatial instability of electromagnetic parameters (dielectric permeability) distribution environments has been developed. The results received with use of developed model, allow, on the basis of dependence of size of a statistical average of a linear error of a fixing on geometrical parameters of an antenna lattice, parameters of relative spatial position of an antenna lattice and a radiation source, to realize possibility of formation of requirements to realization of a considered way of coordinates definition.
To consider possibility of the account of influence of parametres of the environment of distribution of a radio emission on accuracy of definition of a spatial site of a source of radiation at realisation of a way one-item phase coordinates definition.
Carrying out of a quantitative estimation of accuracy of definition of co-ordinates of a source of radiation in the conditions of stochastic character of spatial fluctuations of electromagnetic parametres of environment.
With use of methods of statistical tests the imitating model of process coordinates definition, based on a phase one-item way of definition of a site of a source of radiation has been developed. Results of modelling allow to spend an estimation of dependence of size of a statistical average of a linear error of a fixing from geometrical parametres of an antenna lattice and parametres of relative spatial position of an antenna lattice and a radiation source, considering thus uncertainty of an estimation of relative phase attack of the wave, called both accuracy of gauges, and instability of electromagnetic parametres of the environment of distribution.
The graphic dependences of average value of a linear error of a fixing presented in job for the various parametres characterising both fluctuations of dielectric permeability of environment, and geometry of antenna system, allow to formulate requirements to realisation of a way one-item phase coordinates definition.
