RFI Simulations for testing future SDP imaging workflows

Exploration enabler to: Review existing simulations Extend and onboard as SKA simulation scripts in SKA Gitlab producing a small number of initial data sets. Stretch: Test these data sets using one or more existing RFI flagging codes (eg AO flagger).

We have made significant improvements to the TV transmitter RFI simulation code. The code has been cleaned up and its performance has been improved. We are able to scale it up to simulate multiple transmitters with a larger number of frequency channels. We have made full-sky dirty images to visualise the impact of the RFI. The results are summarised here: https://confluence.skatelescope.org/display/SE/SKA+LOW+low-level+RFI+simulations+for+multiple+emitters https://confluence.skatelescope.org/display/SE/Continued+exploration+of+multi-emitter+RFI+simulations We have investigated the aeronautical and satellite RFI simulation codes written by the SKAO domain specialists, and explored what we need to interface them to the visibility simulation pipelines. The results of this investigation are recorded in SIM-744.
