摘　　要：针对机动作战平台的天线共享需求,本文提出了一种面向雷达-通信一体化的平面阵天线孔径分配方法。首先在平面阵列的基础上建立了共享孔径的模型;其次,将阵元位置的分配转化为多目标优化问题,选择雷达阵列方向图的最高峰值旁瓣电平和通信阵元的信道容量作为优化目标;最后,用改进的遗传算法进行优化计算,并完成了相关的仿真实验。仿真结果证明,雷达最高峰值旁瓣电平和通信信道容量能同时达到工作指标要求,实现了天线孔径的共享。Aiming at the antenna sharing requirement of mobile combat platform,this paper proposes a planar array antenna aperture allocation method for radar-communication integration.Firstly,the shared aperture model is established on the basis of planar array;secondly,the allocation of array element position is transformed into a multi-object optimization problem,and the maximum peak side-lobe level of radar array pattern and channel capacity of communication array element are selected as optimization object;finally,the improved genetic algorithm is used for optimization calculation,and the related simulations are completed.The simulation results show that the maximum peak side-lobe level of radar and the capacity of communication channel can meet the working requirements at the same time,and the antenna aperture can be shared.
