High Resolution Wide Swath SAR Imaging - System Performance and Influence of Perturbations [PDF]

, 2005
The displaced phase centre (DPC) technique enables a wide swath SAR with high azimuth resolution. In classic DPC systems, pulse repetition frequency (PRF), sensor velocity and antenna length underlie a stringent timing requirement to en­sure uniform ...
