The measurement inaccuracies of dispersion diagrams of an arbitrary body in Fresnel zone that arise because of the finite distance between the body and the radiating antenna, and the body and the receiving antenna, as well as the directivity of the antennas are considered. The measurement inaccuracies of dispersion diagrams in the near zone of collimator in case when the boundary wave effect can be ignored are studied.

The first three terms of the asymptotic decomposition of the transfer ration between two antennas with arbitrary directional diagrams and polarization types are obtained. The formulas for the distance that can be used to measure primary and lateral radiation with the given inaccuracy are derived.

Using the mathematical model of dispersion of electromagnetic waves on complex-form objects, the article presents the method of estimating radiophysical parameters of local parts of the surface with claddings, based on the results of measuring angular dependence of effective dispersion surface.

Using the generalized variational principle, the article derives the stationary formulas for metallic body dispersion diagram, with variation going to zero for exact values of surface currents, generated on the body by the primary incident wave.

The calculating the characteristics of radiation of sharp pyramidal horns using aperture integrating when determining the field in a plane discontinuity point using approximating functions will be carried out. The calculation results are compared to the previous ones.
