ESTIMATION OF SOIL MOISTURE WITH RADAR REMOTE SENSING

The radar response to soil moisture content was investigated using a truck-mounted 1-18 GHz Active Microwave Spectrometer system. The sensitivity to soil moisture content and the accuracy with which it could be estimated were evaluated for both bare and vegetation-covered fields. Bare field experiments were conducted to determine the optimum radar parameters (frequency, angle of incidence range and polarization configuration) for minimizing the response to surface roughness while retaining strong sensitivity to moisture content. In the vegetation-covered case, the effects of crop type, crop height and row direction relative to the radar look direct were evaluated.
