Study Influence of Vibration Actions on the Antenna Array Radiation

Discrete mathematical model of the flat waveguide-slot antenna array radiation, taking into account the deformation of its design arising from external vibration actions is proposed. The use of local Cartesian coordinate systems for radiating slits of the antenna array made it possible to determine their new spatial orientation in the global coordinate system after deformation of the design. Calculation formulas convenient for matrix representations are obtained. The results of the study of the influence of vibration actions on the design of the antenna array mounted on a movable object. The estimation of influence of the arising deformations of a design on the radiation pattern the antenna array is given.
