Processing of threedimensional data
Abstract
The problem of adaptive compensation for systematic error in radio interferometer data is considered. The analysis here applies generally only to multielement arrays in which the correlations among all antenna pairs are observed. Given a set of assumptions on the analytic properties of the radio source brightness distribution, and given a mathematical or statistical model of the errors corrupting the data, an optimal estimate is to be made, in some welldefined sense, of the true source brightness distribution. According to a realistic error model, many measurements may have the same component of error; hence one might expect the problem of adaptive error compensation to be tractable, given a minimal set of assumptions. Attention is given to an error model, possible assumptions, an outline of concrete methods, and the implementation of the most convenient method.
