Abstract | Knowledge about soil moisture is important for a number of applications and synthetic aperture radar systems have been shown to be a useful source of data for this information. RADARSAT, with it's
steerable antennae and operational status, can provide timely coverage at a variety of swath coverages and resolutions. However, to make effective use of these various products careful consideration of the differences between the various beam modes
and positions is needed. This paper describes work being done at the Canada Centre for Remote Sensing and the Universite de Sherbrooke to establish an approach to utilize retro-calibration information together with current information inherent in
RADARSAT products to calibrate Standard mode data for soil moisture estimation. Work is also described which is leading to a first order correction for incidence angle as a function of land-cover in an agricultural environment to further develop this
capability of RADARSAT for soil moisture estimation. |
