基于聚类算法的最优子阵划分方法研究
Research on the Optimal Subarray Partition Based on Clustering Algorithm
摘要
Abstract
This paper deals with the optimization of subarray partition operated in large array radar. The theoretical basis of the optimal subarray partition is analyzed based on the principle of minimizing the "residual error" of excitation coefficients. The judgment basis about the contiguous characteristic of the optimal subarray partition is presented, and an innovative approach for subarray partition is proposed. Comparing with the traditional method based on clustering algorithm, the new method can decrease the "residual error" father more, and hold better beam performance. Numerical experiments are reported when the construct of the array and the feed architecture of sum and difference beams are given. Comparing research with two old methods is also presented, and the results demonstrate the efficacy of the proposed methods.关键词
