The Surface Evaporative Duct Height Product: An Evaluation

Abstract

The existence of a surface evaporative duct has many serious operational implications. One of the most serious and obvious implications is that the extended range of the radar will allow distant hostile units to detect the radar(and to be detected by the radar). Thus, the existence of a surface evaporative duct is an important component of the decision on whether or not to radiate. Another consequence of the duct is that a radar hole will exist between the top of the duct and the base of the lobes unaffected by the duct (see figure 1). Hostile aircraft or missiles will thus be able to approach the radar undetected. Conversely, knowledge of the refractivity profile in the vicinity of enemy radars can be turned to tactical advantage.
