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,...

The square kilometre array and the transient universe.

The square kilometre array (SKA) is a next generation radio telescope that will be built in southern Africa and Australasia. It will be built in two phases and will use a range of detectors, from aperture arrays to dishes, to span the frequency range from a few tens of megahertz to a few gigahertz. The combination of great sensitivity, wide field of view and unprecedented computing power mean t...

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...
