DeDop3: A new tool for altimetry data processing

25 November 2015

The recent development of SAR altimetry, or more properly Delay Doppler altimetry, as implemented on CryoSat and soon to be operated on Sentinel-3, opens an exciting new era for the scientific community. This new approach offers scientists an opportunity to develop new processing schemes and derive new and improved products, and so maximise the benefits of the measurements available from upcoming missions.

The DeDop3 project provides the scientific community with the means to understand and use low level altimetry data and to become involved in how these data are processed. This is achieved by providing them with a Fully Adaptable and Configurable DDP and a friendly user interface (a tool) to help them to interact with the DDP. The proposed DDP has different options from which the user will be able to choose according to their particular field of interest.

Examples of the new options are: surface focusing (particularly relevant for special targets like coasts, rivers or lakes), any kind of weighting along and across track, different azimuth processing approaches, stack masking, new stacking algorithms (e.g. ACDC), Sigma-0 at stack level, etc.

The DDP is open source and the code will be freely available, in such a way that users will be able to explore themselves the code and its possibilities and to modify it to their own needs. The key algorithms for the DDP have been developed within the ESA Sentinel-6 project.

The DeDop project team would like to gather input from potential users of the tool to guide its development. If you are interested, please complete this user questionnaire, which also offers the option to sign up for updates on the project.
