摘要：

针对二维不同阵型,研究其二维阻塞矩阵的建立方法。阻塞矩阵因其常用于抑制干扰以及在GSC阵列中阻塞期望信号,因而在阵列信号处理中得到广泛应用。常用的是二项式对消方法,该方法简单有效且具有运算量小的特点。目前,通过二项式对消来构造阻塞矩阵的方法主要集中在一维线阵,涉及二维以及其它阵型的较少。为此,文中将基于二维具有代表性的阵型做了研究,并推导出具有凡导向矢量首项为1的阵型阻塞矩阵构造方法——一字阶梯累积法。仿真验证了该方法的简单有效。

关键词: 二项式对消法, 二维不同阵型, 抑制干扰, 阻塞矩阵

Abstract:

The two-dimensional blocking matrix is established according to the two-dimensional array geometry (including the circular array,planar array,the Y matrix,cross array and L array).Blocking matrix is always employed in interference suppression or blocking desired signal in GSC array.Cascaded column of differencing (CCD) method is a simple and effective method with lower computational complexity,which has been widely used in array signal processing.However,the current study focuses mainly on one-dimensional linear array,while two-dimensional (circular array and plane array) and other formation (Y matrix,cross array and L-array) are rarely proposed,nor comprehensive.This paper studies the representative two-dimensional array geometry in detail and presents a simple method for designing a blocking matrix,namely one-column ladder accumulation.Simulation verifies the feasibility of this method.

Key words: cascaded column of differencing (CCD) method;two-dimensional array geometry;interference suppression;blocking matrix
