Microwave radiometers operating from space are one of the most promising tools for soil, snow and vegetation monitoring, due to sensitivity measured emission surface features extended recursive Earth observation. However, these potentials partially hampered by coarse spatial resolution, which is order tens kilometres, especially at lower frequencies. This paper describes results obtained using a simple algorithm enhancing resolution spaceborne microwave radiometer C-band. The based on smoothing filter-based intensity modulation technique (SFIM), applied Advanced Remote Scanning Radiometer-Earth Observing System (AMSR-E) data collected some reference targets, including Amazon river basin, Lake Victoria in Africa Antarctic plateau.
