The application of an improved SBR algorithm in outdoor environment

Shooting and bouncing ray algorithm is widely used to predict the features of radio wave propagation. Utilizing the features of simulation environment for dynamic emission and tracing can effectively reduce the number of rays that need to be traced, and improve the efficiency of algorithm. This paper proposes an improved algorithm for dynamic emission and tracing rays Based on the existing dynamic tracing method, and the improved algorithm can be used in outdoor environment and with high efficiency.
