This paper characterizes the interferometric phase for a fixedreceiver
bistatic SAR system. Also, the expressions for the
interferometric phase and image resolution cell are summarized.
It will be distinguished between two particular acquisition
geometries : back-scattering and forward-scattering.
A bistatic interferometric chain has been implemented whose
particularities are discussed. The theoretical developments
are complemented with the comparison of the Digital Elevation
Models (DEM) generated from the bistatic interferometric
data acquired with our fixed receiver, named SABRINA
(SAR Bistatic Receiver for INterferometric Applications)
with a SRTMDEM and a Digital Terrain Model (DTM)
from the Institut Cartografic de Catalunya (ICC).
