Optimization of ray tracking algorithm for radio transmission loss under urban terrain

The influence of urban terrain on radio transmission is relatively obvious. How to solve the problem of radio transmission loss in urban terrain is of great significance for improving the communication quality and optimizing the communication network layout. Through the analysis of ray tracking algorithm theory, put forward for the optimization of the algorithm, using the twoway mirror method and particle swarm algorithm improvement optimization, comparative analysis of simulation results, PSO in relatively simple three-dimensional model of two-way mirror method can achieve more than 70% of the optimization effect, achieve the expected research.
