Abstract
At lower frequencies, synthetic aperture radar images can be significantly affected by ionospheric scintillations. In thispaper an approach that combines the Faraday rotation and the autofocus estimation method is proposed, which achieves asuperior performance when compared to using these techniques independently. This improvement is demonstrated withsimulated point targets and airborne data adjusted to the parameters of the Biomass system.
