摘　　要：研究了遗传算法(GA)和时域有限差分法(FDTD)结合来优化智能天线阵列。采用FDTD精确分析考虑互耦影响的智能天线阵,然后结合遗传算法以信噪比为优化基准对加权向量和天线的结构进行了一体化的优化设计,使用Fortran和MATLAB混合编程,优化设计了均匀直线阵和圆形智能天线阵。最后,通过实验天线验证了其有效性。This paper investigates an efficient design procedure integrating the genetic algorithm (GA) with the finite difference time domain (FDTD) for the fast optimal design of smart antenna array (SAA). The FDTD is used to analyze SAA with mutual coupling. Then, on the basis of signal to noise ratio (SNR), the genetic algorithm is applied to optimization of weighting element and structure of SAA simultaneously. The mixed programming for MATLAB and Fortran program is used to optimize linear equally spaced array and smart antenna circular array. Finally, the effectiveness of the analysis is evaluated by experimental antenna arrays.
