Ionospheric effects on synthetic aperture radar (SAR) clutter statistics [PDF]
IET Radar, Sonar & Navigation, 2013 Low‐frequency space‐based synthetic aperture radar (SAR) is an ideal sensor for measuring forest biomass, but can suffer from ionospheric effects. The variation in total electron content (TEC), originating from ionospheric turbulence, causes the along track point spread function (PSF) to degrade in a manner which depends on ...
