GFW 判定為「未匹配 AIS」的 16,170 筆 SAR 偵測，先剔除 3,820 筆風機／平台等固定設施，再以港務局本地 AIS（18,870 艘、推算至 Sentinel-1 過境時刻）重新比對，對上 772 筆假暗船（覆蓋範圍內重比對率 9.5%），剩下 11,578 筆為殘餘暗船；其中 4,209 筆落在本地 AIS 保留期之外，無法驗證。Of 16,170 SAR detections GFW flagged as AIS-unmatched, 3,820 were removed as fixed infrastructure (wind farms / platforms), then re-matched against local Port Bureau AIS (18,870 vessels, dead-reckoned to the Sentinel-1 overpass instant): 772 turned out to be false dark ships (9.5% re-match rate within coverage), leaving 11,578 residual dark detections — of which 4,209 fall outside local AIS retention and cannot be verified.

切片由 Sentinel-1 GRD 影像即時裁切（VV 極化、dB 尺度），判定為自動亮目標偵測結果，長度為粗估。點圖看全解析度原圖。Chips are cut from Sentinel-1 GRD imagery (VV, dB scale); verdicts come from automated bright-target detection and lengths are rough estimates. Click for the full-resolution image.

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.
