摘要
针对进近着陆系统电磁环境逐渐恶化的问题,提出将多种数值计算方法内嵌的模块化设计的电磁环境仿真方法,从模块化仿真模型的建立、模块间的接口及工作流程等方面对进近着陆系统电磁环境仿真做了系统阐述。并利用该方法在Matlab环境下对实际问题进行了仿真分析。研究表明,内嵌了多种数值计算方法的模块化仿真可以实现提前分析和预测复杂的电磁环境对着陆系统性能的影响,对机场的基本设施建设规划具有指导作用。
The electmrnagnetic environment around the modem landing system is becoming deteriorated and available space of the airport is reduced. We put forward a modularized design based method for electmrnagnetic environment simulation, which comprises multiple numerical computation methods for analysis of scattering effects of the objects. For the electmrnagnetic simulation of approach system, the building-up of the modularized simulation model, the interface between different modulars, and the work flow are described systematically. A practical problem is simulated in Maflah with this method and the results are analyzed. The research indicated that the modularized simulation embedded with multiple calculation methods can predict and analyze the influence of complex electmrnagnetic environment on the landing system ahead of time.
