Abstract  

It’s worth to investigate that the false alarm is reduced with polarimetic information while keeping the detection ratio when the fully polarimetic SAR images used for ship detection.According to the nonnegative and sparseness characteristics of eigenvalues,an improved S-NMF (Sparseness-Nonnegative Matrix Factorization) based on eigenvalues is proposed in this paper,which is used for ship detection for SAR images and reduce false alarms effectively.We use the first two eigenvalues to consist matrix for NMF decomposition since they take most of the energy of the targets and could maintain the shapes of the targets,while the sparseness is decided by the clutter distribution,the decomposition result is regarded as Result I which contains all the ships with some false alarms;while the third eigenvalue which could get rid of the false alarms,such as “ghosts” caused by the ship movement,noi,etc.is used to multiply the Result I to get the Result II which could achieve higher TCR(Target-Clutter Ratio).Then the OS-CFAR method is used for ship detection,and become the final detection results.In this paper,this detection algorithm is validated through Radarsat-2 fully polarimetic SLC images of South Sea of China and the corresponding AIS data,and compared with the SPAN method,HV channel image and PWF method.The detection and comparison  results show that the proposed method could not only detection all the ships correctly,but also reduce the false alarms effectively,and has high robustness for non-affected by changes of the detection window.
