Abstract

Knowledge of the soil moisture content is valuable for hydrology and climate studies as well as for yield prediction or agricultural work planning. As part of the long term research plan to establish a relationship between radar backscatter and the spatial and temporal variations of soil moisture, a series of experiments were conducted in the Canadian prairies in 1988.

This paper describes an experiment conducted to examine radar backscatter as a function of soil moisture and plant phenological development. Airborne data were acquired by the Canada Centre for Remote Sensing C-band SAR of a test site near Outlook, Saskatchewan over the course of the growing season. The digitally recorded and processed imagery were externally calibrated via point targets of known radar cross section. Soil dielectric measurements were collected using a portable dielectric probe in fields with similar surface roughness characteristics. These measurements were used as input to a model developed by CCRS for the estimation of soil volumetric water content.

At the symposium presentation quantitative relationships of the radar backscatter to spatial and temporal variations to soil moisture and vegetation will be presented.
