A Statistical Survey of Ionospheric Effects on L-band Sar Data
نویسندگان
چکیده
Recent theoretical analyses of ionospheric distortions in low-frequency SAR signals have indicated many effects that are likely to affect the quality of SAR, interferometric SAR (InSAR), and polarimetric SAR (PolSAR) data (see [1-5]). Faraday rotation, relative range shifts, internal deformations of the image amplitude, range and azimuth blurring, and interferometric phase errors are some of the most significant effects. These distortions affect the quality of SAR data used for other purposes, but they also provide a unique opportunity to study ionospheric events at a fine resolution over large areas.

Faraday Rotation Detection and Correction for Dual-polarization (hh-hv) L-band Data
L-Band SAR, like that on the JAXA’s ALOS PALSAR instrument, is much more susceptible to ionospheric effects than other space based SAR missions, mainly operating in C-band or X-Band. While single-band attenuation of instruments such as the single-polarization JERS-1 SAR instrument certainly occurred, it was rarely noted. With the advent of fulland dual-polarization (full-pol and dual-pol) instr...

Long wavelength Synthetic Aperture Radars (SAR) carried on satellites have enormous potential to provide global measurements of the Earth that are unobtainable by other means. This has excited interest in flying such missions. For example, BIOMASS is a proposed mission for the ESA Earth Explorer Programme that will carry a P-band (68 cm wavelength) radar to measure global forest biomass and pro...
متن کاملEffect of Faraday rotation on L-band interferometric and polarimetric synthetic-aperture radar data
Electromagnetic waves traveling through the ionosphere undergo a Faraday rotation of the polarization vector, which modifies the polarization and phase characteristics of the electromagnetic signal. Using L-band ( = 24 cm), polarimetric synthetic aperture radar (SAR) data from the shuttle imaging radar C (SIR-C) acquired in 1994, we simulate the effect of a change in the Faraday rotation angle ...

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...
