Abstract

A fast and adaptive near-field physical optics algorithm is developed for the analysis of general multi-reflector antenna systems. The algorithm is applied to the radiation pattern computation of an extremely large antenna of RATAN-600 radio telescope operating at mm-wave frequencies. Near-field reflector to reflector field propagation and far-field radiation pattern computation results will be presented and compared with those obtained by geometrical optics with aperture integration.
