Applications for low frequency airborne radars.

ApplicationScopeObservation technique

Forest classification and biomass retrievalBiosphere and bioclimatology studies, especially for terrestrial carbon cycle evaluationSide-looking SAR

Ice sheets soundingGlaciology studies to better describe ice sheet dynamics, which is connected with climate changes and sea level modificationsNadir-looking SAR or cross-track interferometric SAR

Subsurface geomorphology, soil moisture estimation, permafrost, and sea salinity analysisClimate modelingSide-looking SAR (subsurface analyses may require nadir-pointing geometry)

Target detection in forest areasMilitary applicationSide-looking SAR
