摘　　要：在传统的电波传播预测模型的基础上,提出了一种基于射线跟踪法的改进模型。该模型可真正用于除圆形建筑物以外的多棱角建筑物组成复杂微蜂窝区域中场强的准确预测,具有高自适应性、预测精度可有需求控制和高效率等优点。对该模型所得预测结果同文献进行了比较,结果表明该模型具有较高效率和精确度。An improved ray-tracing model based on traditional microwave propagation prediction models is presented . This model can be really used to predict propagation precisely in complicated micro-cell domain formed by multi-edges and corners buildings except circular buildings, which is provided with many advantages such as high self adaptation, prediction preciseness can be controlled by demands and high efficiency. The prediction results by this improved model are compared with references, which indicates the improved model bears higher efficiency and precision.
