摘要
针对机动作战平台天线共享需求,提出了一种面向雷达通信一体化的线阵共享孔径分配方法。首先,建立了共享孔径的模型,根据雷达和通信工作频率差异设计了非均匀线型共享阵列;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,用改进的模拟退火算法进行优化计算,并完成了相关的仿真实验,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要求,实现了天线孔径的共享。
According to the antenna sharing requirements of mobile combat platformsa method for allocating the shared aperture of linear array oriented to radar-communication integration is proposed.Firstlya model of the shared aperture is establishedand a non-uniform linear shared array is designed according to the difference in operating frequencies between radar and communication.Secondlythe position allocation of array elements is transformed into a multi-objective optimization problemand the highest sidelobe level of radar array pattern and the channel capacity of communication array element are selected as optimization objectives.Finallythe improved simulated annealing algorithm is applied to optimization calculationand relevant simulation experiments are completed.The simulation results show that the highest peak sidelobe level of radar and the capacity of communication channel can both meet the working requirementsand antenna aperture sharing is realized.
