| 摘 要： | 利用遗传算法优化线阵波达方向估计性能。优化过程中,不仅优化阵元位置改善方位估计,而且将阵元个数作为优化变量,从而提供了更多的自由度来控制阵列性能。在满足空间谱估计精度的条件下,利用较少的阵元实现超分辨估计。优点是减少信号处理量的同时,简化了设备。仿真实验结果验证了其正确性和有效性。

| Abstract: | Genetic algorithm is used for optimization the performance in estimation direction-of-arrival of linear array.In the process of optimization,not only the position of elements,but also the number is used as variable.This can provide more freedom to control characters of non-uniform linear array.It can use fewer elements to obtain the estimation accuracy of DOA.And it also can decrease the computation amounts and simplify equipment.The simulation results show the validity. |
