Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

The problem of measuring the surface accuracy of a large reflector antenna is not simple. ... Using the Fourier relationship connecting the shape (and phase) of the radiation pattern and the antenna illumination function, a measurement of the former can be used to infer the latter. ... We have performed three set of measures on the CNR-IRA 32-m radio telescope (image) . 1988: Measurements using Misell phase retrieval algorithm, and the 22 GHz Orion water vapor maser as a reference source. ...

... dfosExplorer . ... tar ball of selected tool installation . The DFOS installation tool retrieves a DFOS tool package(s) from a server, unpacks the tar ball(s), and executes a makefile to install the DFOS tool. The tool uses $DFO_INSTALL_DIR to create a subdirectory <tool_name>, under which the tar file is deposited and unpacked. ... If the tool to install has a makefile in its tar file (which is now the standard case), this will be executed and do most (if not all) installation work for you. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
