“…Among the sources of errors are noise, interference by extraneous signals, and self-interference caused by incoherent radiation; the assessment of the system accuracy in the presence of these error sources is a topic of great technical relevance which in the past received considerable attention. In particular, the self-interference by incoherent radiation was studied in connection to clear air turbulence [Valley, 1975;Knepp, 1976], but only recently, it has been recognized that at millimeter waves, the incoherent radiation arising from precipitation particles can also be a source of problems for radio systems owing to possible drawbacks such as extra noise, linear distortion, and &polarization [Ishimaru and Lin, 1972;Capsoni et al, 1976;Olsen et al, 1976;Capsoni and Paraboni, Copyright 1982 by the American Geophysical Union.…”

The incoherent radiation incident on a receiving antenna after having been scattered by raindrops can cause some problems in the case of a monopulse system whose directive pattern presents a deep null toward the coherent incoming wave. This null is then filled with incoherent radiation, therefore giving rise to a degradation of the performances of the measuring equipment. In this paper this degradation is theoretically assessed assuming a simplified geometry (a rain cell embedded in stratified rain); the drops are assumed to be of spherical shape, and typical system configurations for the earth station are considered.
