Description: The method of determination of number and direction of arrival of disturbances signals is examined in the conditions of conducting of experimental researches of descriptions of orientation of aerial in the district of its distribution. A case is analysed, when disturbances signals appear as a result of reflection of эхо-сигналов, radiated the probed aerial from an earthly surface, and the grate of measurings probes is located in a distant area. It is grounded, that in examined case for determining the amount of discrete sources of disturbances signals, arising up on the route of distribution of radio waves between the probed aerial and grate of measurings probes, sufficiently by one vertical line of equispaced grate of receiving probes. The results of design of concrete disturbances situation are resulted on an aerial ground.
