摘　　要：子阵级自适应处理可用较小的代价获得准最优的处理性能．对于幅度锥削的均匀线阵，本文提出用等噪声功率法来划分非均匀邻接子阵，计算机模拟结果表明该子阵结构的自适应方向图保形良好且没有明显栅瓣，其干扰抑制性能接近最优处理．Suboptimum performance may be obtained by partially adaptive processing at subarray level where the problem of how to group the subarrays is an important task. A rule named equal noise power method is proposed to divide a uniform linear array which employs amplitude tapering into contiguous subarrays of unequally sized. A set of results of computer simulation aregiven to show that this subarray configuration has few obvious grating lobes while its adapted antenna pattern and adaptive performance in interference suppression are close to that of the full optimum processing.
