Ship detection using polarimetric synthetic radar (PolSAR) imagery attracts a lot of attention in recent years. Most notably, the detector notch filter (PNF) has been demonstrated to be effective for ship PolSAR imagery, which gives excellent performances. In this work, mathematical form one new PNF (NPNF) based on physical mechanisms targets and clutter is further developed partial targets. Th...

In this letter, the phase compensation method to remove an interfering phase in Pi-SAR-X2 POLSAR data is proposed. This phase is induced when a steep surface is observed by the H and V polarization antennas which are vertically placed. The proposed method removes the phase errors by using the elevation data which is acquired with the slave-V antenna displaced in the cross-track direction (for i...

New methods have been investigated which use fully polarimetric synthetic aperture radar (POLSAR) image data to measure ocean wave slopes. Independent techniques have been developed to measure wave slope spectra in both the radar azimuth and range directions. Wave spectra measured using the new methods are compared with spectra developed using conventional SAR intensity-based methods, and with ...

In developing countries, there is a high correlation between the dependence of oil exports and violent conflicts. Furthermore, even in countries which experienced a peaceful development of their oil industry, land use and environmental issues occur. Therefore, independent monitoring of oil field infrastructure may support problem solving. Earth observation data enables fast monitoring of large ...

A polarimetric coherent Time-Frequency (TF) decomposition approach for ship detection is proposed in this paper. At first, the PolSAR data are decomposed in azimuth direction, range direction only or in both directions. Then a novel statistical descriptor called polarimetric TF coherence indicator, is applied to detect maritime targets in different environments. By using polarimetric RadarSat2 ...
