1. It will provide both scientific user support and a correlator facility. 2. Many filters have been designed to be used with an optical correlator . 3. Common correlator types are the FX and XF correlators. 4. The radar correlator system was activated and the radar scanned the target area. 5. Correlator boards then cross-multiply signals from all tiles to form visibility data.6. Instead, the device for doing the correlation computations was to be an optical correlator . 7. Its primary task is to operate the EVN MkIV VLBI Data Processor ( correlator ). 8. A typical arrangement is the 4f correlator . 9. This technique improves acquisition of the GPS signal and boosts power levels at the correlator . 10. The recordings are then transferred to a central correlator station where the waves are interfered.
