Abstract

Recently, ground marker based on the principle of acoustic detection has become the trend of pipeline technology. As to the difficulty and low accuracy of ground marker, this paper introduces a new MEMS bionic acoustic vector sensor with high sensitivity, good performance in low frequency and lower power. As to the problem of the port/starboard blur of this vector sensor in ground marking, it proposes a new plan and proves the correctness of the plan through theoretic analysis and experimental verification. The results show that the mean error of the directional angle is within 5 degree meeting the needs of the engineering project.

Abstract

The DOA (direction of arrival) estimation of seismic signals from the moving target on the ground bears great significance for unattended ground systems. The traditional DOA estimation of seismic signals is achieved by a sensor array and its corresponding algorithms. MEMS (Micro-Electro- Mechanical Systems) vector vibration sensor, however, gets the vector information over the propagation of seismic signals and therefore can get a DOA estimation within a certain range through a single vector sensor. This paper proposes a new method to extend the orientation range through the rotation of the MEMS vector vibration axis. The experiment shows that this method shares the merits with simple systematic structure, high sensitivity and less than 5 degrees of error on average, which has an extensive wide application prospect. DOI: http://dx.doi.org/10.11591/telkomnika.v11i12.3893
