The error analysis of the localization result caused by the installation errors of a seabed array of magnetometers

摘要

It has a great military significance to detect the magnetic target by magnetic gradiometer system. The positional accuracy of magnetic target will be affected by the installation error of magnetometer in the magnetic gradiometer system. The relationship between the localization results and the installation error is analysed in this paper. The results show that the localization error of magnetic target caused by the magnetometer's rotation can not be ignored. So the localization results of magnetic target should be compensated. The conclusion can be used for automatic correction of the seabed array of magnetometers.
