Picture of the Month


The bistatic polarimetric radar system KAPRI is monitoring the Aletsch glacier. The top picture shows the main device, which acts as a transmitter-receiver and creates a high-resolution polarimetric dataset of the radar scattering properties of the snow cover. The bottom picture shows a secondary receiver placed ~950m away on the terrace of the East Ridge building -- this device allows us to "look" at the radar reflections under a different angle, which adds another dimension to the dataset, and this can subsequently be used for more accurate analysis of the glacier's movements and structure.
