Abstract
Radio Frequency Interference (RFI) can render microwave radiometer measurements useless. We propose a method and an architecture that can be used to identify sources of RFI and be used to identify an optimal scheme for the mitigation of RFI. The system consists of a fully functional digital radiometer that can collect data in the field and pipe the pre-detected signal into, for example, a spectrum analyzer for in-situ analysis or into removable flash memory for later analysis. The digital radiometer employs a Field Programmable Gate Array (FPGA) for employing flexible mitigation strategies. It will also use a programmable noise source for generation of artificial RFI in the laboratory setting, allowing for efficient mitigation algorithm development in a laboratory setting, independent of actual RFI, which may be intermittent. Thus this one instrument can be used to identify RFI, develop mitigation approaches for RFI, and validate the mitigation strategy. A flexible system is essential for this task since RFI takes many forms.
