Time Series of RADARSAT-1 Fine Mode Images Using Sequential Coherent Target Monitoring Software

摘要

Coherent Target Monitoring (CTM) is COTS software that was developed to detect the rate of land subsidence by using Synthetic Aperture Radar (SAR) repeat-pass interferometry applied to persistent scatterers in the scene. DRDC Ottawa has proposed to use the CTM software to produce a time-series of accurately co-registered SAR images and coherence maps that may be used for both non-coherent and coherent change detection. This capability within the CTM software was improved by DRDC Ottawa developing Sequential CTM, whereby the images in the time series are co-registered sequentially in a pair-wise manner. This report documents testing of the Sequential CTM software and includes the time series of RADARSAT-1 Fine mode images that have been processed, as well as processing procedures, some results, and problems that arose. Test sites include Resolute Bay, NV, Kandahar, Afghanistan, CFB Valcartier, and the Miramar, NU mine site.
