Abstract
Purpose
The differential magnetic gradient tensor system is usually constructed from the three-axis magnetic sensor array. While the effects of measurement error, sensor performance and baseline distance on localization performance of such systems have been widely reported, the research about the effect of spatial design of sensor array is less presented. This paper aims to provide a spatial design method of sensor array and corresponding optimization strategy to localization based on magnetic tensor gradient to get the optimum design of the sensor array. Based on the results of simulation, magnetic localization systems constructed from the proposed array and the traditional array have been built to carry out a localization experiment. The results of experiment have verified the effectiveness of magnetic localization based on the proposed array.
Design/methodology/approach
The authors focus on the localization of the magnetic target based on magnetic gradient by using three-axis magnetic sensor array and combine a design method with corresponding optimization strategy to get the optimum design of the sensor array.
Findings

Originality/value

The following text has been added to the beginning of Section 3. Design and optimization of sensor array:
“In this section we rely on the approach to design and optimization of sensor array proposed by Song et al. (2017). It should be noticed that, unlike the article mentioned, we focus on different magnetic target localization methods, and how these two methods use the sampling values of the sensors in the array.”
The authors sincerely apologise to S. Song, X. Qiu, J. Wang and M.Q.-H. Meng for any inconvenience caused.
