Project summary

The project goal is the development of the technology for search and classification of the buried objects causing the Earth magnetic field anomaly, including objects with small magnetization. The accumulated experience of the project participating Institutions, and also other organizations working in this sphere, shows, that magnetic survey is effective, safe, rather reliable and at the same time economical method for detection of the magnetized objects and emptiness in the covering environments. The development of this technique up to a technological level will allow to enhance opportunities of the different object detection.

Detection and noncontact study of the buried objects is the important scientifically applied problem in different fields of industry and science, for example: in geological survey, archeology, defect detection of oil and gas pipelines, road building. Works in this direction are also interesting in the context of ecology as their results can be used at land clearing from the hidden objects of both industrial and military origin. In particular, opportunity for detection of unexploded munitions, and also on former military test sites that allows to prepare them for civil use. Besides this technology can be useful for the on-site inspection tasks within the Comprehensive Nuclear-Test-Ban Treaty. Despite of the last-mentioned aspect, it is assumed that the project developing detection technology is transparent for providing the access to its results that will be provided by the work only with imitating objects, which magnetic properties are known or are preliminary, calibrated. Hardware-methodical foundations of magnetometric search technologies are well-known since 60th years of the last century and it is assumed application and modernization of civil equipment meeting the required limitations. The technology is supposed to be developed up to the level allowing searches in difficult conditions: objects, buried in the ground or being under water, rugged topography, heavy gradient of the magnetic field.

The technology will be based on the multichannel gradient survey technique using absolute magnetometers (measuring devices of the full vector of magnetic induction) together with GPS positioning system, post processing and data interpretation. Magnetometers with Overhauser effect is going to be used as the basic magnetometer at rather high sensitivity and fast response among absolute magnetometers. Particularly, serial magnetometer POS-1, developed and fabricated by SRL of quantum magnetometry of USTU-UPI, which will be modernized for work in a high-speed mode (1-3 measurements per second) are planned to be used for development of the measuring complex. The main originality of the hardware is supposed in implementation of multichannel measurements, i.e. measurements of the geomagnetic field gradient, providing exception of geomagnetic field variations and improvement of the objects detection in covering environments. Thus sensitivity of multichannel magnetometer will be lowered in comparison with serial POS-1 up to 0.1 nT for each sensor (channel) that is physically necessary for increase of speed and surveys authenticity and productivity. Integration of magnetic instruments of the equipment with on-site positioning system (GPS-navigation) is also supposed. Thus, it is planned to equip system with standard land GPS-receivers with accuracy of positioning of 10-15 m. Precision absolute survey is not required under the conditions of task. Accuracy of the relative initial point positioning will be achieved due to application of the additional receiver for differential mode implementation.

The main scientific and methodical task of the project is study and validation of gradient measurements in order to improve the search and classification of the buried objects of small magnetization.

The basic cast list under the proposed project is submitted by "weapon" scientists and experts of the Russian Federation (FSUE academician Zababakhin RFNC-VNIITF USTU-UPI).

Experimental works using the modelling or natural objects will be performed for improvement of this technology. Experimental works will be performed according to application manual for this technology.

The system approach for solving the following related tasks will be used during this project implementation:

  • upgrading of serial proton sensor on Overhauser effect and algorithms for processing of its signal, change of the magnetometer design. Approbation of the proton sensor on Overhauser effect with the raised speed in serial magnetometer POS;
  • development of multichannel magnetometer. Approbation of multichannel magnetometer;
  • combination of a measuring complex with on-site positioning system (GPS-system, or alternative on-site positioning system on the small areas);
  • planning of the experiment for selection of tested objects;
  • preparation of experimental works;
  • development of the software for processing and classification of experimental data with the subsequent interpretation of the obtained results;
  • experimental works on the selected objects;
  • processing of the experimental data and interpretation of the obtained results including 3-D localization of the objects, determination of the assumed weight of the local sources, forecasting of the form and the subsequent classification of the objects;
  • development of a methodical manual for this technology.

The main expected results of works under the project are:
  • development of the technology and improvement of the equipment for object revealing in covering environments using magnetic field measurements;
  • gaining of practical experience for experimental works with a set of objects of the different type;
  • gaining of practical experience for application of the developed technology for search and identification of the buried objects;
  • development of the methodical manual for the developed technology;
  • Creation of the database of the magnetic field anomalies search indicators, caused by the objects of different type.

Additional expected results of works under the project is the possibility of the development on the basis of the obtained materials and practical experience of search techniques, having application economical aspect.

Summarizing of the accumulated experience is also one of the opportunities for continuation of works under the project for providing procedures in the field of on-site inspection within the framework of Comprehensive Nuclear-Test-Ban Treaty:

  • reports for working meetings of the experts on the methodology and equipment characteristics;
  • courses of lectures for training the international inspection groups in the system of the Organization under Comprehensive Nuclear-Test-Ban Treaty.
