Active and Passive Microwave Sensing of Soil Moisture Throughcorn Fields of Varying Density
نویسندگان
چکیده
This paper explores the synergetics of passive and active microwave remote sensing to determine soil moisture under a corn canopy. An experiment has been performed at Alabama A&M Winfield A. Thomas Agricultural Research Station near Huntsville, Alabama in June, 1998. The fields were observed with a truck-mounted L-, Cand X-band polarimetric radar and a second truck-mounted Land S-band radiometer. The paper will present a comparison of active and passive models with the observed data. The effect of the corn in obscuring the soil moisture variations will be discussed.
