As a member of a pulsar search team that works through the Pulsar Search Collaboratory, I've noticed that many data plots (except the tests) are radio frequency interference (RFI) or noise. As a result, I have gained an appreciation for what kinds of issues antennas can cause.

What techniques can satellite ground-station operators, programmers, and installers use to recognize RFI or noise before we have to manually review the plots? How can this problem be reduced or removed?
