Optimization of Outdoor Ray-Tracing Algorithm Based on Artificial Fish Swarm Algorithm

In this paper, the ray-tracing algorithm is used to perform electromagnetic simulation calculation in outdoor scenes, and is improved the simulation accuracy by using an artificial fish swarm algorithm to optimize the model electromagnetic parameters, that reduce the root mean square error value of the calculated power of ray-tracing algorithm and the measured power data for the problem of inaccurate modeling of simulation model electrical parameters. Firstly, the measured data are selectively acquired in the outdoor environment, and secondly, the artificial fish swarm algorithm is used to optimize the range of electrical parameters of the ray-tracing algorithm to improve the electromagnetic calculation accuracy of the algorithm.
