微波天线多场耦合理论模型与多学科优化设计的研究

内容简介：建立了微波反射面天线、平板裂缝天线及有源相控阵天线的多场耦合理论模型，并给出了相应的求解策略与方法，研究了系统误差、随机误差及温度等因素对天线电性能的影响，通过实验验证了模型及求解方法的正确性。最后，通过引入统一的设计向量建立了基于多场耦合理论的多学科优化设计模型，降低了设计工作的重复性，减少了后期的调试难度。

Abstract：The multi-field coupling models of microwave reflector antennas ,plate slot-array antennas and active phased array antennas have been developed in this communication ,based on which the solution strategies and methods are presented to determine efficiently the effects of systematic errors ,random errors and temperature etc .on the electrical performance of antennas .Some exper-iments are performed to validate these models and methodologies .Finally ,a multidisciplinary optimization design model based on the muli-field coupling theory is derived with employing a common design vector ,which can greatly reduce the repetitive works and ease the debugging of products .
