摘要
针对共形阵列雷达导引头波束综合的问题,建立了共形阵列导引头的数学模型。在考虑载体曲率和单元方向图指向差异的基础上,推导出共形阵列远场辐射方向图函数,最后采用遗传算法对此模型的辐射方向图进行了优化。结果表明,这种优化算法对毫米波导引头的波束综合是有效和可行的。
Aiming at realizing the pattern synthesis of conformal array seeker, the mathematical mod- el is developed firstly. Then in consideration of the variable curvature of the platform and different orienta- tions of elements, the radiation pattern function of the conformal array is deduced. Finally, the pattern of the conformal array is optimized by using genetic algorithm. The simulation results are provided to demon- strate the effectiveness and feasibility of the proposed method.
