Simulation and optimization technique for a multi-mirror MM wave reflector radio telescope with FPA

The ray tracing and integral equation methods are used to optimize focal optics and focal plane array configuration of the single, dual and multi-mirror mm-wave telescopes. Simulation and optimization techniques are considered, results being presented for on-axis mm-wave reflector and RATAN-600 radio telescope. Near and far fields of RATAN-600 radio telescope in the multi-mirror mode are studied and optimized with the method of discrete singularities (MDS), which uses the singular electric-field integral equation approach.
