“…In Pol-decomposing detectors, ships are detected by their polarimetric scattering mechanism with the Cameron decomposition (Yeremy et al 2001;Crisp 2004), Krogager and Yamaguchi decomposition (Hannevik 2013), and non-negative-matrix-factorization (Guo et al 2011). Other polarimetric features were also designed as detectors, including horizontal polarisation transmit and horizontal polarisation receive-vertical polarisation transmit and vertical polarisation receive (HH-VV) channel phase difference (Touzi ambiguity removal methods (Velotto, Soccorsi, and Lehner 2013;Wang, Wang, and Liao 2010), and sub-aperture theory (Chen and Wu 2009).…”

Ship detection can be significantly improved by using polarimetric synthetic aperture radar (PolSAR) imaging. In this article, we propose a PolSAR ship detection method based on the use of multi-featured polarization by using the visual attention model. Three polarimetric features, namely, the polarimetric contrast, the polarimetric scattering, and the polarimetric phase, are selected as the early features, and the pros and cons for each feature are discussed. The visual attention model is a framework that rapidly combines multiple features into one feature, which is improved according to the relationship of the selected features. Validation of the method is performed by analysing the multi-resolution process, the improved multi-feature process, the threshold strategy, the sensibility to the incidence angle of the sensors, and the performance of moving ship detection, which are analysed by Radarsat-2 fine quad images with automatic identification system data. Additionally, the false alarm/non-detection analysis and the computation cost analysis are also considered. In contrast to other ship detectors, the proposed detector is more effective and robust.
