GFW 判定為「未匹配 AIS」的 322 筆 SAR 偵測,先剔除 20 筆風機/平台等固定設施,再以港務局本地 AIS(17,217 艘、推算至 Sentinel-1 過境時刻)重新比對,對上 0 筆假暗船(覆蓋範圍內重比對率 0.0%),剩下 302 筆為殘餘暗船;其中 302 筆落在本地 AIS 保留期之外,無法驗證。Of 322 SAR detections GFW flagged as AIS-unmatched, 20 were removed as fixed infrastructure (wind farms / platforms), then re-matched against local Port Bureau AIS (17,217 vessels, dead-reckoned to the Sentinel-1 overpass instant): 0 turned out to be false dark ships (0.0% re-match rate within coverage), leaving 302 residual dark detections — of which 302 fall outside local AIS retention and cannot be verified.
