Zusammenfassung:The temporal coherence of SAR images of forested and cultivated countryside in South East England has been studied using data from ERS-1. Data from the 3 day repeat cycle generally exhibits the highest coherence, and coherent signatures can be used to differentiate between cultivated and forested regions. Data from the 35 day repeat cycle generally exhibits low coherence; broad class separability is possible in the winter but not in summer.
