Numerical simulation of the signal and data processing of the HIPPARCOS satellite.
Abstract
A theoretical study is given of the diffraction pattern which will be obtained with the telescope on board the HIPPARCOS satellite. The output signal is investigated by simulating observations of various stars of different spectral types and classes. For very faint stars, the signal will consist of only a few photons during a sampling interval, so that a statistical recovery of the signal will be needed. A description is given of the simulation of such a signal. Data processing is also considered.
