At the same time, as more and more radio sources have been set up, electromagnetic pollution in urban area becomes more serious, which is harmful to people ' s healthy and communication system so it is necessary to simulate the electromagnetic propagation in urban area by computer being an approximate hf method in evaluating em scattering ， the complex ray method （ crm ） is valuable in actual applications ， mainly benefited from its simple physical model ， convenient mathematical formulation and computational efficiency, especially with the scenes of scattering from complex objects based on the condition mentioned above, a hybrid ray model of the urban area electromagnetic wave propagation prediction was established with the foundation of ray tracing theory and complex ray theory
復射線技術作為一種求解波場問題的高頻近似方法，由於其具有物理模型簡單、數學處理方便、計算效率高等優點，在復雜的目標散射特性分析等應用領域中有著重要的應用價值。基於以上的情況，本文在射線追蹤理論和復射線理論的基礎上，為城區環境建立了混合射線預測模型。本文採用橢圓模型對已有的射線追蹤方法進行加速，並將復射線理論應用到城區環境電波傳播預測中，提出新的預測方法混合射線方法。 -
