  This paper is concerned with the mathematical analysis of experimental
methods for the estimation of the power of an uncorrelated, extended
aeroacoustic source from measurements of correlations of pressure fluctuations.
We formulate a continuous, infinite dimensional model describing these
experimental techniques based on the convected Helmholtz equation in
$\mathbb{R}^3$ or $\mathbb{R}^2$. As a main result we prove that an unknown,
compactly supported source power function is uniquely determined by idealized,
noise-free correlation measurements. Our framework further allows for a precise
characterization of state-of-the-art source reconstruction methods and their
interrelations.
