| Abstract: | Radiowave propagation in atmospheric ducts often demonstrate complicated refraction characteristics.The aim of this article is to analyze the anomalous refractive errors of radaiowave in atmospheric ducts environment.Differential calculation method based on raytracing technology is applied to calculation of true trace of radiowave in evaporation duct and surface-based duct.The abnormal characteristics of refraction errors(such as angle error and height error) in atmospheric ducts are studied by means of simulation.The experimental data of radar detection errors is analyzed to validate the abnormal refractive error. |
