The aim of the campaign was to investigate the effect of different acquisition times for each frequency on the combined information content of the three frequencies in support of the ESA TerraSAR L project.
The circular fields in the image are typical of pivot irrigation systems installed in the area. The light green slice in the circular field located in the upper right of the image illustrates the enhanced radar return due to the wet soil conditions after the pivot boom had passed over the area.
