面向差分阵列的波束形成技术研究综述
A Review of Beamforming Technology for Differential Arrays
摘要
Abstract
Differential beamforming is one of the methods for microphone array signal processing and is widely used in multi-channel speech enhancement,sound source localization and tracking.The traditional differential beamforming adopts a multi-stage cascade structure,and the beam pattern often has the largest directivity in the endfire direction,which is not suitable for the application scenarios where the sound source is located in the non-endfire direction,such as radar,sonar,positioning and tracking.According to the steerable range of algorithm,the steerable differential beamforming algorithms are calssified to three kinds,including non-steerable algorithms,partially steerable algorithms,and steerable algorithms.Aiming at the application scenarios and performance advantages and disadvantages of the three types of steering algorithms,their implementation principles,domestic and foreign research status,and application scenarios are summarized respectively.The principle and basic architecture of the method are introduced.The influence of array formation,spacing and other factors on the steering effect of the algorithm is further comprehensively analyzed,which provides a research basis for application of the steerable differential beamforming algorithm.关键词
