基于Notch窄带波束形成的俯仰角估计仿真

Estimation Resolution Simulation of Pitch Angle Based on Notch Narrow-band Beam Forming

摘要:

波束形成最重要的目的是定向，线列阵的波束形成技术在水声领域中作为接收和检测信号的基本方法已被广泛运用。由于方位估计需要大孔径基阵，而在水中兵器中，为解决小平台目标俯仰角估计问题， 提出一种基于线列阵的 Notch 窄带波束形成方法。主要介绍了基于线列阵的 Notch 窄带波束形成的结构、概念和实现方法，以及基于实测数据条件下的目标俯仰角估计仿真。

Abstract:

As the most important purpose of beam forming is orientation，beam forming technology for linear array has been widely used as basic method to receive and detect signals in underwater acoustic field. Azimuth estimation requires large aperture array，on this account，a novel narrow-band beam forming method based on linear array is proposed. This paper introduces the construction，concept and implementation of Notch narrow-band beam forming based on linear array and estimation resolution simulation of pitch angle based on the measured data.
