Abstract :
Experimental measurements were made under controlled laboratory conditions to determine terrain backscatter in the 40- to 90-GHz frequency range. Terrain samples in a dry and wet condition included asphalt, concrete, gravel, wood, sod, and tall weeds. Smooth and rough water were also included. The 
was established for angles of incidence from normal to 
with the assumption that was frequency independent.
