| Abstract: | From the observed spatial correlation function,we can obtain the source visibility function,and from which we could calculate the high spatial resolution image of the source,finally.In this article,we give our understanding of the process of data processing in the two-element interferometer experiment.At first,the response of the correlation receiver is given.Then a simulation of data processing is shown.Finally,the result of the observed data processing is demonstrated. |
