Abstract

For increased sensitivity in L-band radiome- try, bandwidths on the order of 100 MHz are desirable. This will likely require active countermeasures to mitigate RFI. In this paper, we describe a new radiometer which coherently samples 100 MHz of spectrum and applies real- time RFI mitigation techniques using FPGAs. A fleld test of an interim version of this design in a radio astronomy observation corrupted by radar pulses is described. Mea- surements of the radio frequency environment at L-band from an airborne system are also discussed.
