🎯 SAR×AIS 交叉比對SAR–AIS Cross-Match

What this page shows

GFW 的「暗船」標記是用他們自己的 AIS 來源比對的；本站接的航港局 AIS 在台海近岸密度更高。 本頁把 GFW 標為 unmatched 的 SAR 偵測，拿本地 AIS 重新比對一次 —— 先過濾風機／養殖平台等固定設施， 再把 AIS 軌跡以航位推算內插到衛星過境時刻、用動態半徑做一對一匹配。剩下的才是「驗證後殘餘暗船」。

GFW's "dark vessel" flag is made against GFW's own AIS feed; the local Port Bureau AIS feed is denser near Taiwan. This page re-matches every GFW-unmatched SAR detection against local AIS — first filtering fixed infrastructure (wind turbines, aquaculture platforms), then dead-reckoning AIS tracks to the satellite overpass instant and matching one-to-one with a dynamic gating radius. What remains is the screened residual dark-vessel set.
