STUDY ON OPTIMIZATION OF MECHANICAL AND ELECTRONIC SYNTHESIS FOR THE ANTENNA STRUCTURAL SYSTEM

Integrated optimization design of mechanics and electronics for the hi gh performance reflector antenna is considered in this paper and an ef ficient synthetic method is developed. A general mathematical expressi on of the phase centre for reflector antenna feeds is given. A very us eful formula of a mathematical relationship between the electromagneti c field and the structural deformation of the antenna is then describe d, which provides a good complement for Rutz's formula. Moreover, the paper submits three typically mathematical models for synthetic optimi zation design of mechanics and electronics (SODME) for the antenna str uctural system, on which a good foundation is laid for the realization of SODME in practical engineering. As a demonstration, research work is applied to the design of an 8 m antenna used in a satellite-earth s tation and useful results have been achieved.
