Analysis of RATAN-600 radiation patterns in new operation modes using the MLPO algorithm

The multilevel physical optics (MLPO) algorithm has been adapted to compute radiation patterns of the triple reflector antenna of RATAN-600 radio telescope in new operation modes. These operation modes facilitate tracking of cosmic sources of radiation at arbitrary azimuthal angles in the range of ±30°. The resulting radiation patterns are compared to those obtained via ray tracing analysis.
