Abstract

Interferometrical techniques yield motion along the line of sight. In order to retrieve the three motion components, at least three non complanar LOS vectors are needed. This can be achieved first with ascending and descending orbits and also with different incidence angles or with left right observations. The signal to noise ratios achievable for the different components of the motion (best up down, then EW, and worst NS) using multiple surveys are presented.
