Atmospheric duct is an important environmental factor affecting electronic information systems and the operation of offshore radars or other wireless systems.In this paper,the electromagnetic wave propagation mode of the offshore atmosphere duct was established using the Discrete Mixed Fourier Transform algorithm for the parabolic equation method,and the propagation loss of electromagnetic wave is compared with that for the case of the standard atmosphere,the evaporation duct and surface duct,the results show that the beyond-horizon detection of low altitude Goals can be accomplished by the abnormal propagation of atmospheric duct.

Key words: atmospheric duct;parabolic equation;propagation loss
