Preliminary results of holographic measurements of the 64 meter antenna at Bear-Lake, Moscow-region

摘要

Investigations have been carried into two methods to derive RF performances of large reflector antennas: one method is based on Fourier analysis, the other method on parametric estimation (using maximum likelihood). The latter method needs further work to advance it. Data measured with a 7 m antenna were used for investigations at 11 GHz. Initial holographic data were collected with the 64 meter antenna at Bear Lakes. Preliminary results are presented and some background about the antenna is given.
