High resolution detection, monitoring and analysis of changes using ERS-1 SAR data
Since the launch of the first European spaceborne SAR ERS-1, radar remote sensing is now entering the era of operation. During the commissioning phase of ERS-1, SAR data were acquired on a regular basis over various test sites of the EC, ensuring monitoring of the sites, regardless of cloud cover conditions. This paper first presents a processing strategy for detection of changes occurring to the scene in an ERS-1 time series acquired during several months. Then, careful analysis of the detected changes, related to environmental survey data (meteorology, phenology, land-cover and land-use knowledge) gives some insights into the origin and nature of short and medium term changes in radar backscatter detected by ERS-1. Backscatter changes of different land-cover over the time series are finally exploited for better discrimination between surfaces, through a comprehensive multitemporal ERS-1 SAR data discriminant analysis.
