暗船比對成效Dark-vessel verification

■ 固定設施Infrastructure 3,155 · ■ 本地對上Re-matched 903 · ■ 殘餘暗船Residual 12,595

GFW 判定為「未匹配 AIS」的 16,653 筆 SAR 偵測，先剔除 3,155 筆風機／平台等固定設施，再以港務局本地 AIS（17,220 艘、推算至 Sentinel-1 過境時刻）重新比對，對上 903 筆假暗船（覆蓋範圍內重比對率 6.9%），剩下 12,595 筆為殘餘暗船；其中 496 筆落在本地 AIS 保留期之外，無法驗證。Of 16,653 SAR detections GFW flagged as AIS-unmatched, 3,155 were removed as fixed infrastructure (wind farms / platforms), then re-matched against local Port Bureau AIS (17,220 vessels, dead-reckoned to the Sentinel-1 overpass instant): 903 turned out to be false dark ships (6.9% re-match rate within coverage), leaving 12,595 residual dark detections — of which 496 fall outside local AIS retention and cannot be verified.
