摘要
使用遗传算法(GA)来优化基于圆柱共形的天线阵的方向图,以实现所期望的平均副瓣和指定方向的零陷。作为一种优化算法,它能解决一些N维和非线性的优化问题。首先给出了共形阵列的方向图公式,其次介绍了GA算法和其它阵列综合方法。最后给出了应用实例及其运用不同方法的仿真结果。结果表明,该算法是一种解决多维和非线性问题的行之有效的方法。
To realize desired average sidelobe level （SLL） and null in certain direction, the pattern of cylindrical conformal antenna array was optimized using GA algorithm, which could solve some N dimensions and nonlinear optimized problem. Firstly pattern formula of conformal array was provided, and then, GA algorithm and other array synthesis method were introduced, and at last, application examples and simulation results using different methods were proposed. The results show that the algorithm is an effective and efficient method to solve complicated and nonlinear problem.
