📍 暗船位置分布（SAR 衛星偵測、無 AIS 匹配）

📊 每日暗船數量趨勢

darkship 衛星照片比對報告 Darkship satellite imagery reports 殘餘暗船逐筆裁切 Sentinel-1 SAR 影像，確認海面上是否真的有船 —— 依成像日期列出每張比對切片與判定 Each residual dark detection checked against a Sentinel-1 SAR chip — every chip and verdict, grouped by acquisition date

What this page shows

本頁顯示 SAR（合成孔徑雷達）衛星偵測到、但沒有對應 AIS 訊號的「暗船」。關閉 AIS 不代表船隻消失，仍可能被雷達拍到。SAR 偵測代表雷達可見目標，不必然代表違法活動。

This page shows "dark vessels" — targets detected by SAR (synthetic aperture radar) satellites that have no matching AIS broadcast. Switching off AIS does not make a vessel disappear from radar. A SAR detection indicates a radar-visible target, not necessarily illegal activity.

暗船＝ SAR 偵測到、卻無 AIS 匹配的目標。

Dark vessel = a SAR-detected target with no AIS match.
