| 摘 要： | 微波暗室静区性能的仿真计算通常采用几何光学法,而这种方法对于高频场计算准确性较高,当微波暗室应用于较低频率时,再利用这种方法就会产生较大的误差。文章在探讨两种微波暗室静区性能分析方法的基础上,提出在微波暗室仿真计算时,对于高频段采用几何光学法,低频则采用时域有限差分法。两种分析方法相互补充,能够较好的满足微波暗室静区指标分析的需要。 |
| 关 键 词： | 微波暗室 静区 反射电平 时域有限差分 |

| Abstract: | It is the optical method that analyses the reflection coefficient of anechoic chamber.but the method calculate of high frequency accuracy for this kind of method is higher,being the anechoic chamber to apply in the lower frequency,then make use of this method and will produce the bigger error margin.The article at detailed inquiry into anechoic chamber of two kinds of quiet zone reflectance level function analyzes the foundation of method up,put forward at anechoic chamber imitates,adopt to the optical method for the high frequency,low frequency then adopt FDTD.Two kinds of analytical methods add mutually,can compare good of analytical demand of quiet zone performance in anechoic chamber. |
| Keywords: | anechoic chamber quiet zone reflectance level Finite Difference Time Domain（FDTD） |
