A Method for Circumlittoral Air Intelligence Radar Avoiding Evaporation Duct

Concerned about the evaporation duct is an exceptional refraction in the ocean atmospheric environment,the distribution features of evaporation ducts and its influences on the radar wave propagation were analyzed,and a method of avoiding the evaporation duct was proposed.The theoretical analysis and simulation result shows that the method of avoiding effectively the evaporation duct is to alter the height of radar antenna erected.
