Short summary
This paper describes a radar echo classification scheme, used to identify and remove non-meteorlogical echoes from X-band radar data. The classifier uses fuzzy logic to incorporate multiple radar moments, including linear texture fields, into the decision scheme. The scheme is trained on a limited subset of data from a short field deployment. The feasibility of the scheme is then demonstrated with a range of examples from two field deployments in the UK.
