Abstract
In this paper, the analytical structure of residual 2D phase error in RMA imagery is investigated. By incorporating the inherent phase structure knowledge, an efficient 2-D autofocus algorithm is proposed. The new approach estimates the 2-D phase errors in semi-blind manner, it offers clear advantages in both computational efficiency and estimation accuracy as compared with conventional blind 2-D autofocus algorithms.
