DMFT Parabolic Equation Based Propagation Analysis Considering Ducting and Sea Surface
The propagation path of electromagnetic waves at sea is complex atmospheric refraction and sea surface reflection. In this study, the discrete mixed Fourier-transform parabolic equation method was used to analyze the propagation characteristics of sea-based radar. The atmospheric conditions considered free space and duct atmosphere, while the sea-surface conditions considered flat and rough sea surfaces. The loss caused by the rough sea-surface averaged 1.6 dB in free space and 2.5 dB inside the duct layer, indicating an increase in rough sea-surface loss within the duct layer.
