Within the framework of the ESA SAMOSA Project (SAR
Altimetry Studies and Applications over Ocean, Coastal zones and Inland
waters), innovative physically based models were developed for
near-nadir ocean altimetric waveforms in SAR-Mode and subsequently
implemented in prototype ocean SAR retrackers.
The initial version, SAMOSA-1, included some
simplifications, and was superseded by a theoretically more complete
model, SAMOSA-2. However, this improved model was mathematically
complex and difficult to implement efficiently. Thus it was superseded
by the SAMOSA-3 model, which is computationally more efficient, and has
been adopted by ESA for implementation in the Sentinel-3.

The purpose of this web page is to provide information
on developments and implementations of the SAMOSA-3 echo model:
- to provide details of configurations and
modifications to the SAMOSA-3
model described in the SAMOSA-3 Digital Processing Model
- to provide details on performance of these
implementations through benchmark testing on a test data set.
