| 目的 在保证一定计算精度的前提下，减少有源相控阵天线瞬态热仿真分析的计算时间。方法 使用正交分析方法分析一类毫米波T/R组件中的器件位置、T/R组件尺寸等相关参数。使用极差分析和因素效应分析的方法，分别指出影响简化模型计算精度的几个参数，同时给出可保证一定精度的参数范围。结果 采用所研究的简化方法，对组件和天线阵面均进行了仿真试验对比，结果表明，单个组件温度响应的实测结果和仿真分析结果误差低于11%。采用详细建模的T/R组件和简化的T/R组件进行天线全阵建模的结果最大误差为5.1 ℃，最小误差为1.2 ℃。结论 在W/d<0.8的前提下，对组件中的芯片进行整体建模的简化，其仿真计算的精度无论对于单个组件还是天线阵面的计算均完全满足工程设计需求。 |

| Objective To reduce calculation time for transient thermal and flow simulation of the active phased array antenna in accordance with the certain calculation accuracy. Methods Taguchi method was used to analyze the relevant parameters of the device position, T/R component size and other parameters in a millimeter-wave T/R component. ANOVA and factor effect analysis were adopted to indicate several parameters affecting the calculation accuracy of the simplified model and give the parameter range that can guarantee certain accuracy. Results The method presented was used to simulate and compare component and antenna array. The experimental results show that the error of the measured results of the individual component and the simulation analysis result of the individual components was less than 11%; the detailed modeling of T/R components and The maximum total error of the antenna array modeled by the simplified T/R component was 5.1 ℃ and the minimum error was 1.2 ℃. Conclusion Under the premise of W/D<0.8, the overall modeling of the chip in the component is simplified, and the accuracy of the simulation calculation can satisfy the engineering design requirements regardless of whether the single component or the antenna array is calculated. |
