AbstractPost-harvest agricultural surfaces have varying amounts of crop residue cover, with the amount and type of cover determining, in part, the erodibility and health of the topsoil. If RADARSAT is to be used to map residue and/or tillage in order to monitor soil conservation practices, an understanding is required of the relationship between residue and radar backscatter. During the Fall of 1996, an experiment was conducted on agricultural plots at the Agriculture and Agri-Food Canada Central Experimental Farm in Ottawa. The experiment was designed to address the importance of residue type (corn and barley), residue moisture content and residue amount to radar backscatter, and to examine the effect of look direction on radar response. Scatterometer measurements (C- and L-Band with 4 linear polarizations) were made over corn and barley plots with treatments varying by residue amount and moisture level. Soil and residue moisture data were collected during 9 days of scatterometer acquisitions. This paper describes the preliminary results on the relationship between residue characteristics and C-Band radar backscatter, which demonstrated that using RADARSAT and ERS-2 configurations, some information can be provided on residue management practices.
