Preliminary Specifications for the Square Kilometre Array

End-to-end compute model of the Square Kilometre Array

Scientific requirements for next-generation radio telescopes significantly influence compute requirements of their processing facilities. For future instruments, such as the Square Kilometre Array, seemingly minor changes can easily push compute requirements into the exascale domain. We present a model for engineers and astronomers to understand these relations and to make trade-offs in radio t...

Meeting the Calibration Requirements for the Square Kilometre Array

Calibration of the Square Kilometre Array (SKA) will be the key to successfully achieving an astronomical instrument two orders of magnitude better than existing radio telescopes. The extent to how accurate the calibration data should be is dependent on the sensitivity of the processing algorithm to errors, or its robustness. The SKA telescope calibration data will be sensitive to many factors,...

Simulating full-sky interferometric observations

Aperture array interferometers, such as that proposed for the Square Kilometre Array (SKA), will see the entire sky, hence the standard approach to simulating observed visibilities will not be applicable since it relies on a tangent plane approximation that is only valid for small fields of view. We derive the harmonic representation of the visibility function observed by an aperture array inte...
