基于正四棱锥形六元声阵列被动定位的研究
Research of Passive Acoustic Location Based on Rectangular Pyramid Array of Six Sensors
摘要
Abstract
An acoustic localization wireless sensor network node uses the time difference of arrival( TDOA) theory to locate acoustic targets. It proposes a rectangular pyramid array with six sensors. The paper deduces the formulas of the target spatial orientation and uses Generalized Cross-Correlation algorithm to achieve time delay estimation. The paper analyzes the model error. Finally,through the simulation experiment,the target can be effectively positioning and the model error is small.关键词
