An Estimate of the Temperature Field of the Curvilinear Reflector of an Antenna under Unsteady Conditions

A mathematical model of the formation of the temperature field of the curvilinear reflector of a microwave antenna under unsteady conditions is proposed, based on an analytical solution of this problem for the individual faces of a polyhedron, which approximates the surface of the reflector. An esti...

Description
Summary:A mathematical model of the formation of the temperature field of the curvilinear reflector of a microwave antenna under unsteady conditions is proposed, based on an analytical solution of this problem for the individual faces of a polyhedron, which approximates the surface of the reflector. An estimate is made of the varying temperature field, taking into account the nonuniform heating of the surface by solar radiation, and also the corresponding changes in the directional characteristics of the antenna.[PUBLICATION ABSTRACT]
