Ionospheric correction of InSAR data for accurate ice velocity measurement at polar regions
Interferometric synthetic aperture radar (InSAR) is a widely used tool for measuring ice sheet velocity in the Polar Regions. However, the ionosphere is a prevalent source of noise in these data. Ian Joughin is a co-author of a study, published in the May 2018 issue of Remote Sensing Environment, where a split-spectrum technique was utilized, and its performance analyzed, for correcting ionospheric effects in InSAR-based ice velocity measurements in Greenland and Antarctica. Read on to learn if the technique effectively reduced noise level…
