Multi-temporal backscatter and target-to-clutter estimates for several micro-environments

A multi-temporal study of backscatter variability from environmental changes, is presented here for Radarsat images centered on an Atlantic-Canadian region. This study region has distinct seasonal climate variation and several types of environmental features. Both environmental features and man-made targets are studied. This paper presents backscatter results in relation to the environment. Overlapping the image collection time period, a hydrographic experiment was conducted in the same area. The measurements from this hydrographic study were recorded daily (e.g.; soil moisture and meteorological data) and are compared with the multi-temporal backscatter statistics in this paper. Most of the backscatter results here indicate a decreasing trend in backscatter from the spring to autumn seasons, and a sharp backscatter increase at the onset of spring
