| 摘 要： | 针对声相关计程仪的测速特点,研究了一维、二维基阵的设计方法。一维基阵采用基于约束最小冗余的设计方法,可以获得比均匀线阵大得多的阵列孔径,从而提高基阵的利用率,但约束最小冗余线阵(RMRLA)的设计方法计算量巨大,并不适合二维基阵的设计。在重新定义冗余因子,建立理想位置矢量图模型,提出位置矢量重合率等概念的基础上,实现了适用于声相关测速需求的二维基阵的快速设计。仿真结果证明了该设计方法的可行性。

| Abstract: | A design method of one dimension and two dimension arrays for an acoustic correlation log(ACL) is studied.Based on the method of restricted minimum-redundancy linear array(RMRLA),non-uniform linear array has significant performance in comparison with uniform linear array,such as extending aperture and full utilization of sensors.But the algorithm does not adapt to two-dimensional arrays design due to huge computation and the imperfection of the positional vector set.In this paper,the redundancy factor is re... |
