In article results of imitating modelling of the basic characteristics of an orientation of convex antenna lattices are received. The estimation of the diagramme of an orientation on capacity on various distances to a supervision point is spent; the maximum factor of the directed action of a convex antenna lattice at variable distance to a supervision point; dependences of a relative error of definition of near border of a distant zone on range by known criteria. Questions of definition of near border of a distant zone of a convex antenna lattice on various parametres are besides considered. Dependences of characteristics of an orientation of convex antenna lattices on geometrical parametres are received at peak distributions used in practice. Dependences of parametres of diagrammes of an orientation of convex antenna lattices on width of angular sector of excitation are found at various kinds of peak distributions.
Keywords: protuberant aerial grate, distant area, diagram of orientation, coefficient of the directed action, main maximum, level of lateral petals, imitation design, gain-phase distributing
