Abstract

A method to mitigate radio frequency interference (RFI) in weather radar data may include computing p norms of radials of weather radar data to construct an p norm profile of the weather radar data as a function of azimuth angle. The weather radar data may include Level 2 or higher weather radar data in polar format. The method may include determining that a given radial in the weather radar data is an RFI radial based on the p norm profile of the weather radar data. The method may include displaying an image from the weather radar data in which at least one of: the RFI radial is identified in the image as including RFI; or the RFI radial is omitted from the image.
