Array configuration studies for the Square Kilometre Array - Implementation of figures of merit based on spatial dynamic range
Abstract
The Square Kilometre Array (SKA) will be operating at the time when several new large optical, X-ray and Gamma-ray facilities are expected to be working. To make SKA both competitive and complementary to these large facilities, thorough design studies are needed, focused in particular on imaging performance of the array. One of the crucial aspects of such studies is the choice of the array configuration, which affects substantially the resolution, rms noise, sidelobe level and dynamic range achievable with the SKA. We present here a quantitative assessment of the effect of the array configuration on imaging performance of the SKA, introducing the spatial dynamic range (SDR) and a measure of incompleteness of the Fourier domain coverage () as prime figures of merit.
