This paper presents an initial analysis of the possibilities for
velocity and acceleration m
easurement with the Bi-
Directional SAR imaging mode (BiDi). It comprises single
satellite single path acquisitions as well as a constellation of
two satellites. The translati
onal velocity components into
azimuth and range directions are simulated. A BiDi ap-
proach for measuring the azimuth velocity from one satellite
with one receiving channel is proposed. Image examples
acquired with the TerraSAR-X (TSX) and TanDEM-X
(TDX) satellites show velocity and acceleration effects on
ships and the proposed BiDi ve
locity approach is verified.
Interferometric fringes were
observed on anchoring ships. A
first approach into the understanding of rotational effects
was achieved by simulation of rotational fringes.
