| Abstract: |
Interference from active users of the radio spectrum will always be a problem for radio astronomy, but careful planning, active data monitoring, and a few data editing techniques allow us to use more spectrum for science than one might expect. A good plan starts with knowing what to expect in the frequency range that you want to use. Then there are a number of receiver options, signal processing configurations, and observing strategies that will help to minimize the effects of interference to your data. The degree to which you can remove interference from data after it is recorded depends considerably on having chosen the best observing parameters before the observing run began. Research into real-time signal processing for interference excision offers some hope that future radio astronomy receivers will better separate cosmic signals from man-made transmissions. Some of these excision techniques under investigation are reviewed. |
