GFW 判定為「未匹配 AIS」的 17,499 筆 SAR 偵測，先剔除 3,677 筆風機／平台等固定設施，再以港務局本地 AIS（18,303 艘、推算至 Sentinel-1 過境時刻）重新比對，對上 746 筆假暗船（覆蓋範圍內重比對率 10.5%），剩下 13,076 筆為殘餘暗船；其中 6,690 筆落在本地 AIS 保留期之外，無法驗證。Of 17,499 SAR detections GFW flagged as AIS-unmatched, 3,677 were removed as fixed infrastructure (wind farms / platforms), then re-matched against local Port Bureau AIS (18,303 vessels, dead-reckoned to the Sentinel-1 overpass instant): 746 turned out to be false dark ships (10.5% re-match rate within coverage), leaving 13,076 residual dark detections — of which 6,690 fall outside local AIS retention and cannot be verified.

資料來源與限制：AIS 可能因轉發延遲或船舶走暗而不完整；SAR 偵測代表雷達可見目標，不必然代表違法；可疑分數為風險排序，並非法律認定。本報告由公開資料自動產生。
Sources & limits: AIS may be incomplete due to relay delay or vessels going dark; a SAR detection is a radar-visible target, not proof of illegality; the suspicious score is a risk ranking, not a legal finding. This report is auto-generated from public data.
