METHOD AND SYSTEM FOR ELECTROMAGNETIC DETECTION AND SURVEY OF TERRITORY WITH RESPECT TO METAL HAVING DISTURBING ACTION OF MASS Russian patent published in 2020 - IPC G01V3/10 F41H11/136 

FIELD: physics.

SUBSTANCE: present invention relates to the field of electromagnetic detection and examination of the territory with respect to metal masses which exert disturbing action, which lie hidden under the ground surface, primarily for detection of unexploded ordnance. In group of inventions consisting of electrically non-conductive material bogie (1) is used as bearing structure for matrix of excitation coils (11), located at least with partial overlapping in plane x-y, and several three-coordinate receivers (12), which are substantially distributed in the plane of excitation coils (11) and uniformly distributed at least over their entire area and/or even partially behind the overlapped by at least one excitation coil (11) region, wherein excitation coils (11) are successively switched, and all three-coordinate receivers (12) detect the pulse response attenuation pattern on all three spatial axes (x, y, z).

EFFECT: technical result is increase in working width while maintaining efficiency.
