One of the breakthroughs from the AgriSAR campaign has been the development and testing of new filtering methods. These new methods are improving the appearance and applicability of C-band radar images provided by satellites such as Envisat and, in the future, Sentinel-1 for land applications.
These images show the same multi-temporal radar composite acquired over the Flevoland test site in the Netherlands. The grainy appearance of the left image is characteristic of radar images and often a limiting factor in using them at high resolution. The right image demonstrates how a new mathematical technique based on multiple images, which was improved in the campaign, can dramatically enhance the appearance of the image and data quality.
