Abstract

We report the new experimental data on the development of the radio holography diagnostics method application to the mirror antenna system with an adaptive surface. Measurements were performed on the “South sector with Flat reflector” antenna system of the RATAN-600 radio telescope. We were able to obtain the high repeatability of reconstruction for both amplitude and phase distribution of the electric field over the antenna aperture due to the stabilization of speed of the reference panel movement used to produce a linear phase shift. We present the resuls of modeling of the considered method application to the space telescope with an adaptive surface on the example of the Millimetron project. The applicability of the method to the dignostics of full steerable telescopes is shown.

AB  - We report the new experimental data on the development of the radio
holography diagnostics method application to the mirror antenna
system with an adaptive surface. Measurements were performed on the
“South sector with Flat reflector” antenna system of the RATAN-600
radio telescope. We were able to obtain the high repeatability of
reconstruction for both amplitude and phase distribution of the
electric field over the antenna aperture due to the stabilization of
speed of the reference panel movement used to produce a linear phase
shift. We present the resuls of modeling of the considered method
application to the space telescope with an adaptive surface on the
example of the Millimetron project. The applicability of the method
to the dignostics of full steerable telescopes is shown.
