摘要
This paper addresses anomalies that occasionally appear in SAR images. The cause is assumed to be atmospheric inhomogeneities. The atmospheric effect is small and should be more noticeable at longer ranges. A first order model of the SAR image formation process is developed. This model predicts secondary effects in the image that are not directly observed. The secondary effects are attributed to coupling between the image and frequency (data) space.
