For each pass, there is a minor problem in terms of
covering the whole Taiwan island completely by the 4-beam
electronic scanning scheme. We won’t rule out to have more
beams in the antenna design later for saving the cost of
implementing the satellite rotation capability. It is assumed that
we will have this satellite rotation capability (see the agility capability in Table I), and the satellite can be
the suitable position before the imaging. A
targets in the whole island can be easily acqu
these strips. In order to establish a mi
architecture, it is required to evaluate the link
four beams. Table V shows some quickly
based on the established SAR algorithms.
