The during may02, experiment A1578 (wim van driel) had problems with radar like rfi between 1360 and 1374. These were being caused by the FAA radar at 1350 Mhz. For those that aren't familiar with how the correlator works, I thought i'd give a little more detail.
the freq range of the sbc | 1362.75 to 1375.25 |
The Faa radar frequency | 1350 Mhz |
The 50 Mhz digitized band sky range | 1344 to 1394 but it is flipped by 3 hi side lo's so Dc=1394, 50Mhz=1344 |
Offset 1350 from bottom of Dc band | 1394-1350= 44Mhz |
