| 为了提高大规模发射阵列的优化效率和降低大规模发射阵列的散热压力，提出了一种基于子阵和交替迭代的大规模发射阵列稀布阵方法。首先给出了大规模发射阵列基本子阵结构的确定原则，接着建立基于基本子阵结构的优化模型，之后交替迭代地对基本子阵结构的中心位置进行优化，在优化过程中各基本子阵结构的中心位置的移动总是使得发射阵列方向图函数的最大旁瓣最小。仿真实验表明，提出的大规模发射阵列稀布阵方法能够较快地收敛到较优的结果。 |

| Abstract: |
| In order to improve the efficiency of optimizing the configuration of large scale transmitted array and reduce its heat dissipation pressure,a method for sparsely optimizing large scale transmitted array configuration based on subarray and alternate iteration is proposed. Firstly,the fundamental principle of the subarray configuration for sparsely optimizing large scale transmitted array is presented. And then,the optimization model is constituted based on subarray. Finally,the positions of subarray elements are optimized in the form of alternate iteration with the proposed optimization method and the final movement of each subarray results in the minimization of the maximal sidelobe of the beamforming pattern of the large scale transmitted array in the optimization process. The computer simulation shows that the proposed optimization method can fast converge toward good result. |
