  Mass and radius measurements of stars are important inputs for models of
stellar structure. Binary stars are of particular interest in this regard,
because astrometry and spectroscopy of a binary together provide the masses of
both stars as well as the distance to the system, while interferometry can both
improve the astrometry and measure the radii of the stars. In this work we
simulate parameter recovery from intensity interferometry, especially the
challenge of disentangling the radii of two stars from their combined
interferometric signal. Two approaches are considered: separation of the
visibility contributions of each star with the help of differing brightness
ratios at different wavelengths, and direct fitting of the intensity
correlation to a multi-parameter model. Full image reconstructions is not
attempted. Measurement of angular radii, angular separation and first-order
limb-darkening appears readily achievable for bright binary stars with current
instrumentation.
