Signal correlation in an interferometer |
| | The output of a multiplier is the amplified power of the input signals from a pair of antennae. |
| |  |
| |  |
| | The power from each antenna, for a source of flux density S, is |
| |  |
| | The voltage waveform from each antenna is |
| |  |
| | Inserting these, we obtain for |
|  |  |
| | The quantity that really interests us here is the uncertainty of |
, 
. The derivation of this quantity was described by Ravi Subrahmanyan during the last workshop (notes are available online). | |
