Combined modeling of the shape of the surface of the grid canvas belt stretched on the wireframe and statistical radar characteristics of the calibration reflector has been performed. To solve the problem, a complex computer model is proposed and implemented. The model provides analysis of the stress state of the grid canvas belt forming the surface of the folding spherical reflector, numerical electrodynamic calculation of the spatial backscattering diagram and estimation of statistical radar characteristics corresponding to the arbitrary location direction in the process of observation. Using the complex computer model, the equilibrium shape of the reflecting surface has been calculated for the selected design version of the folding spherical reflector, the facet 3D electrodynamic model has been developed, spatial backscattering diagrams have been calculated and statistical RCS characteristics for various wave sizes of the object have been evaluated. The presented complex computer model may be used in studies related to analysis of radar characteristics of calibration folding spherical radar reflectors with various versions of power wireframe design.
