Abstract: new radio frequency interference (RFI) filter algorithm for weather radars is proposed in the two-dimensional (2D) range-time/sample-time domain. Its operation in 2D space allows RFI detection at lower interference-to-noise or interference-to-signal ratios compared to filters working only in the sample-time domain, while maintaining very low false alarm rates. Simulations and real weather radar data with RFI are used to perform algorithm comparisons. Results are consistent with theoretical considerations, and show the 2D RFI filter to be a promising addition to the signal processing arsenal against interference to weather radars. Increased computational burden is the only drawback relative to filters currently used by operational systems.
