P-SAR

P-SAR operates in a stripmap mode with a swath illuminated by a single antenna beam, i.e. an imaging configuration similar to that of the ERS-1/2 SAR. Global coverage is obtained by the interleaved stripmap operations among three complementary swaths as described previously. The beam re-pointing is performed through a roll maneuver of the spacecraft, as there is ample time over the poles for such operations. This solution using the spacecraft rolling was preferred over the possibility of electronic beam switching due to its simplicity. (en)
