Abstract:

Considering the cost and the complexity in the design of large array antenna, subarray partitioning is introduced. However for lacking of analysis, very simple partitioning strategy is usually adopted in practice, which extremely restricts the performance of the radar system. The equivalence relation of the optimum subarray partitioning and clustering for the monopulse technology are revealed. Then the theory to solve subarray partitioning by clustering algorithms is established, and the monopulse technology at subarray level and its performance index are induced. The proposed subarray partitioning method based on clustering can get the optimum subarray configuration effectively. Numerical experiments about the proposed method and comparing research with the classic method are presented, and the results demonstrate the efficiency of the proposed method.
