The Use of Spaceborne Imaging Radar-C (SIR-C) Data for Long-Term Monitoring and Change Detection
Abstract
The Spaceborne Imaging Radar-C (SIR-C) acquired polarimetric SAR data during two 12-day shuttle missions flown in 1994. SIR-C was unique as it was the only mission in the mid-90s that acquired multifrequency data in both C-band and L-band and had a global coverage. RADARSAT and ERS missions that operated in the 90s collected data only in the C-band. L-band data, such as the ALOS Palsar data, were operationally collected much later. SIR-C therefore serves as a very valuable dataset from the mid-90s to compare SAR data acquired in the later years, in support of long-term monitoring and change detection studies.
The Alaska Satellite Facility (ASF) is in the process of generating high-resolution image products from all SIR-C data that could be produced as part of its SIR-C data recovery effort. The georeferenced products will find wide us in application studies such as a decadal scale change analysis due to urbanization, deforestation, or coastal erosion. Both C-band and L-band SIR-C data will be processed, expanding the benefit for the broader user-community.- Publication:
