Study at 1046 megacycles per second of the reflection coefficient of irregular terrain at grazing angles

An experimental d etermination of the reflection coefficient over rough te rrain is r epo rted .The reflected signal received over rough terrain is considered to be mad e up oft wo components, one that is a specular component and the other a R ayleigh-distr ibuted componen t.Where one term inal is low, the Rayleigh component is considered to be small with respect to the sp.ecular component ?lIt increas:s in relative magnitude as the height of the lower te rJl?ln almcreases.A tenmnal h eIght IS reached where the specular component is no longe r ~Hgl11~Cant, and the refl ected energy is esse ntia lly Rayleigh-distributed .A t erm inal height I S qUickly reached a,?ove which the m ea n valu e of the reflected energy is relatively constant, of a low value, a nd md epend ent of the g razing angle.
