The Interferometer on the sun house
H. G. Thum (DK2KA)
If one wants to create detailed images of astronomical radio sources, antennas with high angular resolution are needed. High angular resolution can only be achieved using large telescopes, but these have limits in their mechanical design. The limit for moving telescopes is a diameter of 100 m, whereas fixed telescopes can be built up to 300 m. If one wants to achieve a higher angular resolution, this can only be achieved by interlinking these telescopes (interferometry).

SAT-dish
A setup with camping telescopes of 35 cm width is sufficient taking measurements of the Sun and Moon. With offset-mirrors of 1.2 m width more than 10 astronomical objects are detectable. Parabolic antennas become expensive when the sizes exceed the standard ones. At a size of more than 1.2 meters the mechanics becomes costly. A mirror of 1.2 meters has an aperture angle of about 1.4 degrees. With winds even a 60 mm antenna mast moves. A change in position of the telescopes of 15 mm results in a phase reversal, which cancels out the signal. No measurements are possible in strong gusty wind.
Particularities of the measurements of OrionA, M42
H. G. Thum (DK2KA)
During the Orion measurement from 2/23/2014 to 3/7/2014, puzzling signals were registered on 3 separate days (2/24 to 2/26). For the Orion measurements the antenna was set to 34.2°, which is also the range in which geostationary satellites are positioned. The finger-frequency determined with the interferometer corresponded to that of astronomical objects. A search for this object in the star charts turned out negative. There was simply no object in this celestial region that could produce such high measurement signals. Could these reflections be from satellites?

Moon
Besides our Sun, the Moon is the object in our solar system that has significant radiation powers. In lunar measurements, the continuum radiation and the measurement of finger-frequency are easily traceable without interference. The Moon, being relatively close to earth at 384400 km, has a large area, making its thermal radiation well detectable. The Moon is identified at 42000 Jansky, which during FFT analysis results in a measured value of 3.8.
