A significant obstacle to their widespread adoption is the expensive and power-consuming ADC required at gigahertz frequencies. To mitigate these challenges, employing low-resolution ADC, such as one-bit, has been suggested. Nonetheless, using one-bit sampling results in the loss of essential information. This study explores two RD imaging methods in PMCW radar systems utilizing NN. The first method merges standard RD signal proce","authors_text":"Changxu Zhang, Jingxian Wang, Markus Gardill, Moritz Kahlert, Tai Fei, Zhaoze Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2025-03-17T05:38:39Z","title":"High-Resolution Range-Doppler Imaging from One-Bit PMCW Radar via Generative Adversarial Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.12841","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":"sha256:890798f9791291e78c08888e0a320124f96d83b1c528cb7fced2adf31a7edef5","target":"record","created_at":"2026-07-05T10:32:47Z","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":"3e369a1fc2f12713a4603b39e85beb4fc9d6c3c4cb12fcf1547cb15bc9d5f447","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2025-03-17T05:38:39Z","title_canon_sha256":"5d7a993ab8216527d3f2bd5a063cb1232e15b06c1c02e1bd27933c7bc1a087b9"},"schema_version":"1.0","source":{"id":"2503.12841","kind":"arxiv","version":1}},"canonical_sha256":"a73a5ce79518776db17f2a74cde25fb00d520e2c13b1c47653e48ce33f5869f2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a73a5ce79518776db17f2a74cde25fb00d520e2c13b1c47653e48ce33f5869f2","first_computed_at":"2026-07-05T10:32:47.646425Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:32:47.646425Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1izp38XaLCVwbGhEfCJEDhYrwmvUdir/kexAsw733yhVfJf2h7O/rKMa5xKM22WKT7Tg9I3TYvOKOzTUI1zRDg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:32:47.646910Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.12841","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:890798f9791291e78c08888e0a320124f96d83b1c528cb7fced2adf31a7edef5","sha256:8d96c8f41de450f4a0648b131e68337cecb8ce8a47ccfd5dbd3ca282a1438f23"],"state_sha256":"e7c28e312add43c6dedbe9f92fbc44330821bf658cf83e4608e4ddebe727b777"}
