Abstract :
The power response of a two element IF correlation interferometer to a point source of broadband random noise is expressed in terms of the crosscorrelation function of the signals from each element. This representation separates clearly the effects of element spacing, element radiation pattern and system bandwidth on the overall performance. Results are derived for systems with and without RF preselection. Implementation of an interferometer by means of a wideband polarity coincidence correlator is described, This approach permits the use of digital data processing techniques.
