Abstract :
Since a motion error is the main phase error source in the aircraft synthetic aperture (SAR), the motion errors have to properly be compensated during the SAR image reconstruction. The chirp scaling (CS) algorithm is one of the best algorithms in the practice system. An improved CS algorithm which can compensate motion error is proposed. Specially, the proposed method is based on the constant acceleration movement and the sub-aperture technique.
