Assessing the RFI environment of the DSA-2000

The Deep Synoptic Array DSA-2000 is a future survey radio telescope that will operate in the 0.7-2 GHz range. This frequency band is almost fully allocated to active services, which makes it challenging to radio astronomy operations due to the high probability of radio frequency interference (RFI). This paper provides a comprehensive list of RFI in the DSA-2000 band, and describes the protocol employed to establish it. It also summarizes the RFI mitigation strategy currently planned for the future telescope.
