Evaporation duct is a kind of typical anomalous profile of atmospheric refractivity, it can partly trap electromagnetic waves, as a result, the propagation characteristics are changed, which may be applied in electronic equipments such as radar, communication and ECM, etc. The purpose of this article is to study on anomalous characteristics of electromagnetic waves in evaporation duct environment through simulation methods based on electromagnetic waves propagation parabolic numerical equation and split-step Fourier algorithm technology. The experimental data of radar abnormal detection in Dalian Sea Area in October of 2003 is analyzed as an example of application to validate the abnormal characteristics of the electromagnetic waves and the anomalous detection of radar influenced by evaporation ducts.
