Abstract :
The radar backscatter coefficient 
of alfalfa was investigated as a function of both radar parameters and the physical characteristics of the alfalfa canopy. Measurements were acquired with an 8-18 GHz FM-CW mobile radar over an angular range of 
as measured from nadir. The experimental data indicate that the excursions of at nadir cover a range of nearly 18 dB during one complete growing cycle. An empirical model for was developed, which accounts for its variability in terms of soil moisture, plant moisture, and plant height.
