Surface-Search Radar Performance in the Evaporation Duct: Global Predictions. Revision A

Abstract

Surface-search radar systems, if properly designed, may utilize the oceanic surface evaporation duct to detect surface targets at ranges greater than 60 nmi. Theoretical relationships between the thickness of the evaporation duct and maximum detection range are derived for four radars at frequencies of 3, 6, 10, and 18 GHz. Distributions of maximum detection range are calculated from two worldwide duct height climatologies. The analysis considers four targets with three possible radar cross section distributions applied to each target. Since rigorous full mode waveguide analysis of all combinations is impractical, the propagation characteristics are approximated using two single mode techniques. Keywords include: Surface-search radar; Global predictions; Free Space S election Range (FSDR); and Free Space Detection Path Loss (FSDPL).
