Abstract
As it has been shown in [1], the tropospheric duct may affect significantly the wideband propagation due to the different conditions the frequencies of an, even narrow, range propagate in this case. The wideband distortion may be of particular importance for short pulse radar systems or high bit rate communication systems. In this report the influence of the commonly occurring evaporation ducts has been studied for two frequency bands: 10–12 GHz and 17–18 GHz. A path loss prediction program, described and validated in [2, 3], has been used to calculate the propagation channel transfer function (field strength relative to free space as a function of frequency) in the presence of a homogeneous evaporation duct.
