... Up: Data Processing Systems . ... One of SIM's key issues is to develop a new algorithm for calculation of fringe parameters. Not only astrometric results need that new algorithm, but also real-time fringe tracking requires a new method to calculate phase and visibility fast and accurately. The formulas for the phasor algorithms for fringe estimation are presented. ... The advantages of phasor algorithms for application of fast fringe tracking and on-board data compression are discussed. ...

Phase Retrieval Measurements of Antenna Surfaces Using Astronomical Sources Bojan Nikolic, John Richer, Richard Hills Mullard Radio Astronomy Observatory, Cavendish Laboratory, Cambridge, U.K. Abstract We present a novel technique for accurate measurement of the largescale errors in an antenna surface using astronomical sources and detectors. Out-of-focus images of compact astronomical sources contain a wealth of information about the telescope optics. ...

... Since image restoration algorithms are highly sensitive to the accuracy of the calculated PSF, a significant portion of our research effort is devoted to accurately modeling the PSF which is a highly non-linear problem. Our approach is based on analytical modeling of the wavefront phase using Zernike polynomials. ... In the Fourier domain, we scale the phase map by an observed PSF to more accurately account for the HST/FOC combination. ... The final result is an improved estimate of the phase map. ...
