为了抑制稀疏阵列方向图的栅瓣，提高分布式星载雷达阵列方向图的性能，对相同子阵组成的稀疏阵列方向图综合进行研究，提出了一种基于相同子阵的稀疏阵列方向图综合算法。首先对子阵级稀疏阵列进行建模，并对其阵列方向图的特性进行分析。然后通过优化子阵级稀疏阵列，实现对方向图栅瓣的抑制。最后通过仿真，验证了该算法的有效性。
為瞭抑製稀疏陣列方嚮圖的柵瓣，提高分佈式星載雷達陣列方嚮圖的性能，對相同子陣組成的稀疏陣列方嚮圖綜閤進行研究，提齣瞭一種基于相同子陣的稀疏陣列方嚮圖綜閤算法。首先對子陣級稀疏陣列進行建模，併對其陣列方嚮圖的特性進行分析。然後通過優化子陣級稀疏陣列，實現對方嚮圖柵瓣的抑製。最後通過倣真，驗證瞭該算法的有效性。

In order to suppress the grating lobe of sparse array pattern and improve the performance on array pattern of the distributed spaceborne radar, this paper studies comprehensively the pattern synthesis of sparse array that is composed of the identical subarray, and presents a synthesis algorithm of sparse array pattern based on the identical subarray. Firstly, the sparse array at the subarray level is modeled and the characteristics of its array pattern are analyzed, next, the grating lobe of pattern is suppressed by optimizing the sparse array at the subarray level, and finally, the effectiveness of this proposed algorithm is verified by simulation in this paper.
