Webformation of a ground level cloud. This type of fog occurs more particularly in valleys. The attenuation by a radiation or convection fog is expressed by the following relation: 3.3 – Rain attenuation Rain attenuation (dB/km) is generally given by the CARBONNEAU relation [4]: 1.076*0,67 Att R rain= 3.4 – Snow attenuation WebChaff cloud RCS modeling. Radar cross section (RCS) is a measure of the return or scattering power in a given direction. Because of the chaff cloud signal attenuation, the chaff inside chaff cloud can’t received signal energy like the chaff near chaff cloud surface, so the former’s RCS is smaller than the latter.
