Interferometric array assessment: Investigating UV coverage and imaging

Image quality assessment technology is introduced to assess interferometric array. Including existing assessments of Interferometric array, four categories of array assessment methods are concluded: assessing UV coverage directly, assessing UV coverage related to observing objects, assessing imaging quality related to observing objects and assessing imaging quality directly. A specific method in each category is proposed. All methods are used to design or optimize interferometric arrays, especially the early-stage study of Solar Low Frequency Array.
