Specifically, we partition these data into statistically homogeneous subsets by identifying possible clutter power variations with respect to the cells under test (accounting for possible range-spread targets) and/or clutter edges. To this end, we consider different situations of practical interest and formulate the classification problem as multiple hypothesis tests comprising several models for the operating scenario. Then, we solve the hypothesis testing problems b","authors_text":"Alfonso Farina, Chaoran Yin, Chengpeng Hao, Danilo Orlando, Gaetano Giunta, Linjie Yan, Silvia Liberata Ullo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2023-02-16T16:01:47Z","title":"Classification Schemes for the Radar Reference Window: Design and Comparisons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2302.08384","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6175422de0d64b2d126278ecfce60181e2627cc149f42d9defcca80586b9ed69","target":"record","created_at":"2026-07-05T05:42:37Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c034e5e9b3546dd26ebaec8e560dac3dbbc87d4dffdbcb4b5ab0020a75900fe2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2023-02-16T16:01:47Z","title_canon_sha256":"785d243e1029747233923e5e55a4b61d52569d14e80b361a5489ce7847aaeaa5"},"schema_version":"1.0","source":{"id":"2302.08384","kind":"arxiv","version":1}},"canonical_sha256":"478ed3e729548ea9041ba36c0a8e19374bff859bb5f96c31a4f3bd400a3896bd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"478ed3e729548ea9041ba36c0a8e19374bff859bb5f96c31a4f3bd400a3896bd","first_computed_at":"2026-07-05T05:42:37.529305Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:42:37.529305Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k/+x6kzHxDnv8kayfJeeMFz7KQTGNz27AalGbBDIWlRj+IiIG69rreHEtrgZ1mze8jOzUxXmTNqZx4djk+mIDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:42:37.529781Z","signed_message":"canonical_sha256_bytes"},"source_id":"2302.08384","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6175422de0d64b2d126278ecfce60181e2627cc149f42d9defcca80586b9ed69","sha256:fa38c432c4ff954988ed8b040406801e6dcad8d0d4874f0e038efe8b56549d85"],"state_sha256":"00dca790771f9e676d2e39401095fcd4d957ccd012fc9e2cd4389808e16e4123"}
