Abstract
The advancement of ship detections is an important focus of
Maritime Domain Awareness. Improvements in both speed
and correctness responses to events can be made by introducing
new ship detection methods. Sentinel-1 imagery has
recently been released for public usage and with it the chance
to test new methods on current data. By exploiting the fact
that ships are locally bright objects, this paper presents a
method for ship detection within Sentinel-1 imagery using
the H-dome transform. This transformation, typically used
to highlight sub-cellular structures in biology, can be used to
flatten clutter around the ship and highlight the brightest section
of ships. The method was tested against two Sentinel-1
images in both HH and HV polarization with a total of 82
ships. The method provided improved FAR over the conventional
CA-CFAR method at the cost of slightly worse
detection accuracies. Future work includes using the method
as auxiliary data in other ship detection methods.
