基于遗传算法的圆柱共形微带天线阵的综合

Synthesis of Cylindrical Conformal Microstrip Antenna Array Based on GA

针对基于梯度信息的经典阵列天线的综合方法一般不能直接应用于共形天线阵的综合,文章采用遗传算法,以圆柱共形微带天线阵为例,进行了共形阵波束形成的研究。提出了根据目标方向图,通过构造特殊适应度函数的方法达到优化目标。计算机仿真结果表明,遗传算法对共形天线阵方向图的灵活控制简便有效。

To synthesize cylindrical conformal array, traditional approaches based on information of grads are inapplicable for applying directly. In order to solve the problem, Genetic Algorithms （GA） is adopted in text in study the shaping of wave beam of conformal arrays, synthesis of cylindrical as an example. A novel approach was proposed, in this approach, with the target of the pattern of wave, via constructing extremely function of Fitness approaches optimized target. Simulations has shown that, Applying GA for optimizing conformal arrays is convenient and effective.
