Triad-cluster models of typical random antennas

In the paper ontological situation model (OSM) of aperture and distributed random antennas (ARA and DRA) statistical simulation using the triad-cluster method (TCM) is presented. The ways of solving inner and outer problems, including the formulation of the initial conditions and the technique for studying characteristics of the electric and magnetic field strength vectors for TCM-models of ARA and DRA based on triad elementary radiator (TER) are considered. An idea of using a three-dimensional analogue of the Huygens-Kirchhoff principle in random radiating system simulation based on triad-cluster method is proposed. The fact that statistical properties of electromagnetic fields and excitation currents that appear in TCM-models of ARA and DRA correspond to the applicability conditions of the generalized central limit theorem is proven. The criteria for selecting the initial conditions for SS, stochastic combinatorics of TCM and the laws for random errors distribution are formulated.
