The Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection
The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
متن کاملShip Detection with Sar Data Using a Notch Filter Based on Perturbation Analysis
The aim of the work described in this paper has been the development of an innovative ship detector, based on synthetic aperture radar (SAR) polarimetry and the methodology pioneered in [1-3], namely perturbation analysis. Ship detection is a key topic for the surveillance of coastal areas. In particular, SAR presents an advantageous technology, since the observations are independent on weather...
متن کاملShip detection and characterization using polarimetric SAR
Polarimetric information is investigated for ship detection and characterization at operational satellite SAR incidence angles (20◦ to 60◦). It is shown that among the conventional single channel polarizations (HH, VV, or HV), HV provides the best ship-sea contrast at incidence angles smaller than 50◦. Furthermore, HH polarization permits the best ship-sea contrast at near grazing incidence ang...
متن کاملShip Detection in Polarimetric SAR Based on Support Vector Machine
In this study, we propose a Support Vector Machine (SVM) based method for ship detection in polarimetric SAR (POLSAR). Because of similarities of ship and man-made structures on land in scattering mechanisms, land and sea are first segmented by SVM according to polarimetric features and texture features; The SVM-based Recursive Feature Elimination (RFE-SVM) approach is adopted to improve the pe...
متن کاملDetection of Ship Targets in Polarimetric Sar Data Using 2d-pca Data Fusion
Data fusion has lately received a lot of attention as an effective technique for several target detection and classification applications in different remote sensing areas. In this work, a novel data fusion scheme for improving the detection accuracy of ship targets in polarimetric data is proposed, based on 2D principal components analysis (2D-PCA) technique. By constructing a fused image from...
