摘　　要：本文在介绍了电波传播预测的射线跟踪法 ,根据建筑物体对电波的反射和透射的特点 ,结合射线跟踪法 ,提出了一种室内物体的分块模型 ,设计了射线跟踪的递归算法 ,根据这一方法可以计算出当发射点在室外而接收点在室内时室内各处电波传播的路径损耗。实验结果表明 ,预测结果与测量结果符合很好。Ray tracing is a useful tool for propagation prediction By using features of reflection and refraction by objects of building,a patched model combined with ray tracing technique is presented The accuracy of prediction has been improved The software that can give the path loss of any site inside the building has also been developed Results of calculation agree well with measurement
