Abstract :
The ratio of specularly reflected to scattered power received by a radar altimeter is shown to be related to a parameter q = (4K2/¿0 ß2), where K is the Fresnel reflection coefficient, ¿0 is the differential scattering coefficient, and ß is the effective beamwidth. The critical range of rms surface roughness is shown to be from 0.1 to 0.335 ¿ for examples from 100-ns-pulse aircraft radar to 10-ns-pulse spacecraft radar over water.
