摘要
射频环境仿真是电子战仿真的重要内容,而射频环境效应的仿真是射频环境仿真的关键。该文通过讨论和分析射频环境效应(杂波、多路径、衍射、大气折射和大气吸收)的原理和算法,旨在建立综合的射频环境效应模型。重点讨论了高斯谱的W eibu ll杂波算法;分析了标准多路径和衍射算法,并介绍了SEKE算法;讨论了大气折射的射线追踪算法和等效地球模型;介绍了计算氧气和水蒸气吸收的方法;针对某些算法给出实际应用中的建议。最后,在JMASE平台中实现了面向对象的综合射频环境效应模型,从而可为射频电子战仿真提供较真实的仿真射频环境。
The simulation of RF environment is an important aspect bf EW simulation, and the simulation of RF environment effects is its crucial element. By discussing and analyzing the principles and algorithms of RF environment effects (clutter, muhipath, diffract)on, atmosphere refraction and attenuation), this paper tries to provide a general RF environment model. Algorithm for the Weibull clutter with Gauss PSD is discussed. A standard muhipath and diffraction algorithm is analysed, and the SEKE algorithm is introduced. The radial - tracing algorithm and the effective earth model are discussed. Algorithms for the absorption of oxygen and vapor are introduced. For certain algorithms, some practical advice is given. Finally, an object -oriented general RF environment effects model is realized in JMASE, which can provide relatively authentic simulated RF environment for the simulation of RF EW.
