Abstract

PURPOSE:To compensate the influence of the induced magnetism of the earth magnetic field different by the form of the vehicle main body, by installing a magnetism detector and a detector for attitude on the moving vehicle. CONSTITUTION:Exploring detector 3, electronic circuit 4 for detector 3, detector 5 for attitude, electronic circuit 6 for detector 5, and operation processing part 7 are mounted on vehicle main body 1. Exploring magnetism detector 3 is affected by exploration target 2, earth magnetism 13, and induced magnetism 14 of main body 1. Detector 5 for attitude is affected by earth magnetism 13 and induced magnetism 15 of the main body. The difference between the output of electronic circuit 4 and the output of electronic circuit 6 is operated by operation processing part 7 to take out only the signal of exploration target 2.
