| 摘 要： | 在阵列信号处理中，大型阵由于系统结构复杂，成本较高，在实际应用中受到限制，而采用子阵结构则可以减少接收通道数，简化系统设计，降低成本。本文针对等幅均匀线阵提出了一种新的结构简单的子阵，并且通过打乱子阵排列的周期性以及保证各子阵输出噪声功率相等，该子阵的栅瓣效应几乎可以忽略且其自适应方向图保形良好。

| Abstract: | For array signal processing technology,the application of large-sized array is restricted because of its complex structure and its high cost.But using subarray can decrease the number of the receiving channels,simplify the system design and reduce the cost.For constant amplitude homogeneous array,a new subarray whose configuration is simple is proposed,and its grating lobes unobvious and its adapted antenna pattern close to that of the full optimum processing by confusing the periodicity of subarry and making the power of output noise equal. |

| Keywords: | subarray full adaptive processing grating lobe |
