Microwave radiometers operating outside the protected portions of the frequency spectrum can be adversely impacted by radiofrequency interference. We describe a new radiometer which coherently samples 100 MHz of spectrum and applies real-time RFI mitigation techniques using FPGAs. A field test of an interim version of this design in a radioastronomy observation corrupted by radar pulses is described. Experiments currently in progress to demonstrate the system in ground-based remote sensing are also detailed.
