Two computationally attractive parameter determination approaches are provided to maximize the array gain under certain constraints. In addition, the applications of the multi-point OPARC algorithm to array signal processing are studied. It is applied to realize array pattern synthesis (including the general array case and the large array case), multi-constraint adaptive beamforming and quiescent pattern control, where an inn","authors_text":"Bin Liao, Xiang-Gen Xia, Xuejing Zhang, Xuepan Zhang, Yue Yang, Zishu He","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-12-29T01:28:56Z","title":"OPARC: Optimal and Precise Array Response Control Algorithm -- Part II: Multi-points and Applications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.10090","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":"sha256:1f8b6c0e508dc4ef57748f7aa4e730f7f3d1aa68ea6742cf6db3e0e81cb0ae07","target":"record","created_at":"2026-05-18T00:27:03Z","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":"3cc38c89e46a610ad2904c4b7b282efcdb3868d2a63267bb8ab49fae544825ce","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-12-29T01:28:56Z","title_canon_sha256":"a6cde5fa29fad5620af0425d8eb7aa40ce531a33279fd66140ef7662ee848941"},"schema_version":"1.0","source":{"id":"1712.10090","kind":"arxiv","version":1}},"canonical_sha256":"13a8a3208a970d23e527b0665ce9a1a54bfeeea21c5abb0759697b28308d6e61","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"13a8a3208a970d23e527b0665ce9a1a54bfeeea21c5abb0759697b28308d6e61","first_computed_at":"2026-05-18T00:27:03.979263Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:03.979263Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fAd9cPUcMJ/R0ojONLZFz20m/Qcpnj8F3ZjSnJ0zAV1CL9Qgh2R4J+lJoC5Le7I/MNe9eBqbURbxyuVmxIYqAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:03.979825Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.10090","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1f8b6c0e508dc4ef57748f7aa4e730f7f3d1aa68ea6742cf6db3e0e81cb0ae07","sha256:c3f7a72aba6a67b5ec7a89c1d2e28ef8f084c8250829bd64b1235f70cca15677"],"state_sha256":"8e468d25c03db04cb5aeda56f76f74aab75f2891a9ac82edb332543527d9e303"}
