Developments Of Rfi Detection Algorithms And Their Application To Future European Spaceborne Systems

For many years Radio Frequency Interference (RFI) has been an increasing problem especially for spaceborne radiometers; as a result, there has been an increasing effort on developing algorithms and hardware for counteracting RFI. Due to the amount of time it takes to develop and build spaceborne systems, this development has had a limited effect on current spaceborne systems. In spaceborne radiometer systems currently being built the need for on-board detection and blanking of RFI has been acknowledged. This paper addresses the efforts to implement RFI detection and blanking techniques on European operational spaceborne systems, MetOp Second Generation (MetOp-SG) satellites and the Copernicus High Priority Mission Passive Imaging Microwave Radiometer (CIMR) satellites.
