利用海洋环境中大气波导的参数化模型及电磁波传播的地型抛物方程,建立电磁波传播正问题,获得电磁波传播功率损耗.结合正演模式,通过遗传算法反演出大气波导参数,并对遗传算法参数的设置进行了讨论,对反演系统进行了抗噪能力的分析.发现当误差小于10%时,遗传算法仍能保持较高的反演精度;当误差大于10%时,该算法的精度开始受到显著的影响.研究结果可能会对雷达仪器设计和应用提供参考.
Based on the parametric model of atmospheric duct in the ocean and the ground-type parabolic equation of electromagnetic wave propagation, a positive problem of electromagnetic wave propagation is established and the power loss of electromagnetic wave propagation is obtained.According to the forward model, the atmospheric waveguide parameters are retrieved by genetic algorithm, and the genetic algorithm parameters The anti-noise ability of the inversion system is analyzed.It is found that the genetic algorithm can still maintain high inversion accuracy when the error is less than 10%, and when the error is greater than 10%, the accuracy of the algorithm starts The research results may provide a reference for radar instrument design and application.
