Abstract
The Maritime Domain Awareness initiative seeks to constantly
improve the ways in which maritime information is
collected. With the recent release of free Sentinel-1 imagery
to the public, monitoring the maritime environment has become
a more affordable. Using the basis of a cell-averaging
constant false alarm rate prescreening method as input, this
paper presents a novel method for detecting ships within Synthetic
Aperture Radar imagery using a Gabor wavelet correlator.
The method proposed allows for any configuration of the
filter bank and prevents false detections by processing possible
targets at a local scale. The method was tested against two
Sentinel-1 images in both HH and HV polarization with a total
of 82 ships. The method provided significantly improved
FAR over the conventional CA-CFAR method at the cost of
slightly worse detection accuracies in some cases. Future
work includes further analysis of the method parameters to
determine their effects on the performance of the proposed
prescreening method.
