Interference noise spectrum above a rough sea surface at small glancing angles

Spectral and correlation characteristics of fluctuations of a point radiation source bearing under strong effect of a sea surface in W-band range

“…In such a manner one would explain a faster drop in the correlation level with an increasing distance when the sea-way period decreases and therefore the shifting of the extremum toward the lesser distances. The similar results that enter into the treatment of fading effects were obtained in [2].…”

“…In such a manner one would explain a faster drop in the correlation level with an increasing distance when the sea-way period decreases and therefore the shifting of the extremum toward the lesser distances. The similar results that enter into the treatment of fading effects were obtained in [2].For systematizing of results we have used a wave parameter L)eA(hl+h2)/(2DJDA) having the meaning of unevenness correlation radius (in our case it is /Ih, one-half of the sea wave length) to the first Fresnel zone longitudinal dimension ratio [3]. The use of Dr in the distance distributions &do) has led to "resonance" dependence coincidence along the abscissa axis and allowed to construct empirical curves limiting the region in which all the experimental &do) values obtained for various sea surface states.…”
