A critical review of the mission requirements [R-3] is described. Emphasis is put on limitations and requirements put on the geophysical models for the baseline system parameters and observation geometry in order to meet the user requirements.

A review of forward models (mono- and bistatic) for NRCS, DCA and SAR wave spectra is provided, and necessary improvement and extension to be implemented in Task 2 are defined. A similar approach is applied to retrieval schemes to be implemented in Task 3.

Of particular importance is the necessity of a synergetic approach to the retrieval of wind, wave (partly) and current fields.

Simulations show that very accurate estimates of local wind vector and wind sea waveheight are needed in order to meet the requirement of an accuracy of retrieved surface current speed of ൑ 0.3 ݉/ݏ . The baseline observation concept to consider is shown in Figure 1.
