Conformal antenna array dynamic subarray partitioning method and direction of arrival estimation method

The invention discloses a conformal antenna array dynamic subarray partitioning method and a direction of arrival estimation method. The methods include first determining k initial clustering centers, distributing the k initial clustering centers to subarray clusters (represented by the clustering centers) most similar to the centers according to the similarity (distance) between array elements and the clustering centers, then calculating the clustering center of each new cluster (the average value of all objects of the clustering center), repeating the process till a standard measure function begins converging. By means of the methods, the problem that an antenna carrier rotates in direction of arrival (DOA) estimation is solved.
