A new technology of aperture shadowing calculation for a large space radio telescope mirror

A new technology of aperture shadowing calculation for large space radio telescope mirror is proposed in the framework of geometrical optics. The technology exploits the possibilities of Solid Works package and is applied for the aperture shadowing calculation of a plane wave and for the total aperture shadowing of the 10-meter mirror of the space telescope “Radioastron”. This work is partially supported by the Russian Science Foundation for Basic Research (project 07-08-00482).
