Ship Detection of Polarimetric SAR Images Using a Nonlocal Spatial Information-Guided Method |

|---|---|---|
Ship detection of polarimetric synthetic aperture radar (PolSAR) plays protection. Over the past years, local spatial infor mation around pixels has been successfully applied to this task.However, few works have been done on PolSAR ship detection using nonlocal spatial information (NSI). Within this context, we here propose one NSI-guided ship detection method PMR. Briefly, the feature power difference (PD) is first constructed by computing the total PD between the center pixel c and its most similar nonlocal pixel i within a 7 x 7 window. Then, the polarimetric feature reflection symmetry (RS) is introduced into PD to construct the method PMR (i.e., PD Multiply RS) for further enhancing the target-to-clutter ratio (TCR) and improving the ship detection accuracy. Experiments carried out on three real PolSAR datasets show that, in comparison with some other methods, especially the recently proposed local neighborhood information-based ship detector PWFN, PMR is more apt r foship detection. On average, its figure of merit (FoM) and TCR values respectively surpass PWFN 0.24 and 12.83 dB. |
