ABSTRACT X-ray polarimetry missions like Imaging Polarimetry Explorer will be able to measure for the first time polarization properties of accreting, weakly magnetized neutron stars in low-mass binaries. In this work, we present simulations expected polarized signal, including coronal emission different geometries corona itself, i.e. a slab above accretion disc and spherical shell around star....

The first step of pre-processing of SAR data involves the conversion of slant range to ground range multi looking process and polarization synthesis. The latter step involves generating 2×2 scattering matrix which can be used to synthesize the radar return with any transmit/receive polarizations and thereby measuring the complete information of the earth feature. This chapter is divided in two ...

Based on the foregoing lectures respective applications of both Polarimetry and Interferometry will be presented. From he large palette of possibilities which includes global mapping with space borne SAR and the establishment of digital terrain models with high accuracy, observation and to some extent prediction and forecast of natural disasters (involving landslides caused by earthquakes ore a...

ESPaDOnS is a new-generation cross-dispersed échelle spectropolarimeter, the commissioning phase of which is scheduled at the Canada-France-Hawaii Telescope (CFHT) for spring 2004. This instrument will provide full coverage of the optical domain (370 nm to 1,000 nm) in all polarization states (circular and linear) at a resolving power of about 70,000, with a peak efficiency of 20% (telescope an...

Random noise polarimetry is a new radar technique for high-resolution probing of subsurface objects and interfaces. The University of Nebraska has developed a polarimetric random noise radar system based on the heterodyne correlation technique. Simulation studies and performance tests on the system confirm its ability to respond to phase differences in the received signals. In addition to polar...

Aims. The aim is to study structure and polarization properties of the stars and planet systems in the active Orion H II-region. Methods. We performed AO-assisted high-resolution imaging polarimetry on selected Orion proplyds close to the Trapezium stars in the J, H, and K bands. Differential polarimetric images of one of the largest and brightest proplyds are interpreted using 3D radiation tra...
