Chinese researchers have published details on a new ship-tracking technique using low-resolution satellite images.
The team allegedly tested their technique on open source, publically available satellite images and were able to find some larger U.S. naval vessels.Chinese researchers have allegedly developed a new technique for tracking ships at sea using low-resolution, open-source, “free” satellite images. By searching for tell-tale ship wake patterns, the team’s new algorithm can rapidly find ships that are otherwise invisible to the naked eye.
Yet despite this, the team, led by Hong Jun of the Dalian Naval Academy, said it had discovered a U.S.behind the ships , a simple technique that could be used by almost any country or organization. Different ships create distinct wave patterns on the sea surface, similar to fingerprints.However, accurately identifying specific U.S. warship models requires sensitive parameters.
A ship’s wake can extend up to tens of kilometers. For Hong and his colleagues, even blurry satellite photos could contain helpful information to identify vessels. Navies have often used aerial and satellite imagery for this task, the results of which can then be analyzed. This technique is vital for naval surveillance and reconnaissance, especially for
