Research on the representation of environmental electrical parameters based on limited measured date
Aiming at the problem of low environmental adaptability of ray-tracing algorithm,a characteriza-tion method of environmental electrical parameters based on limited measured data is proposed.Genetic algorithm and ray-tracing algorithm are combined.Based on the test of field data in a limited area,the optimal electrical pa-rameters of the target environment are given which improve the prediction accuracy of the ray-tracing algorithm in this scenario.The simulation results show that this method saves a lot of time in field test on the basis of improv-ing the adaptability of the ray-tracing algorithm.In general,a reliable method is provided for the efficient develop-ment of electromagnetic environment situational awareness.
