Analysis of Background Ionospheric Effects on Geosynchronous SAR Imaging
Background ionospheric propagation effects are adverse to the performance of Geosynchronous Synthetic Aperture Radar (GEO SAR) system. This paper focuses on the background ionospheric phase advance, which can be modelled as a function of slant total electron content (STEC). The dispersive feature of the phase advance caused by the background ionosphere could be able to distort the GEO SAR range...
متن کاملNumerical Analysis of Orbital Perturbation Effects on Inclined Geosynchronous SAR
The geosynchronous synthetic aperture radar (GEO SAR) is susceptible to orbit perturbations, leading to orbit drifts and variations. The influences behave very differently from those in low Earth orbit (LEO) SAR. In this paper, the impacts of perturbations on GEO SAR orbital elements are modelled based on the perturbed dynamic equations, and then, the focusing is analyzed theoretically and nume...
متن کاملStudy of Ionospheric Effects on Azimuth Imaging for Medium-earth-orbit Sar
The Medium-Earth-Orbit SAR (MEOSAR) is one of the most potential next-generation spaceborne SARs for its excellent performances. However, the MEOSAR may not be able to produce data useful for science applications due to ionospheric effects. So it is very necessary to study ionospheric effects for the development of MEOSAR. In this paper, we present ionospheric effects on azimuth imaging for MEO...
متن کاملthe effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
15 صفحه اولAn Improved Polar Format Algorithm with Performance Analysis for Geosynchronous Circular Sar 2d Imaging
This paper presents an improved polar format algorithm (PFA) for geosynchronous synthetic aperture radar which undergoes a near-circular track (GeoCSAR). GeoCSAR imaging geometry and signal formulation considering orbit perturbations were derived to ensure accurate slant range between antenna and targets. The illuminated area is more than one million square kilometers due to the long slant dist...
