Multielectrode automated electroprospecting complex IDNAKAR

Multielectrode automated electroprospecting complex "IDNAKAR"The complex "Idnakar" allows to determine the location and spatial characteristics of soil objects, detect the change of layer character and within-layer objects made of various materials . The complex "Idnakar" can be used to search soil hollows (pipelines, cellar, catacombs, etc.). Areas of possible use: archaeology, criminal law, search of underground communications, diagnostics of the state of pipelines, constructions.

The automated electroprospecting complex "Idnakar"allows to determine the location and spatial characteristics of soil objects, detect the change of layer character (natural and antropogeneous inhomogeneities, processed soil) and within-layer objects made of various materials (ferrous and non-ferrous metals, bone, ceramics, stone). The complex "Idnakar" can be used to search soil hollows (pipelines, cellar, catacombs, etc.).

Measurements technique is based on the original method of multigrid resistivity survey. In comparison to the known instruments adaptive measurements algorithms, which on the one hand, eliminate redundancy of the information, and on the other - ensure specific accuracy of measurements depending on selected measurements algorithm and data computing, are used in the complex. By the results of operations in the sphere of automation of resistivity survey soil investigations 4 patents on the equipment and measurement technique using adaptive algorithms were obtained.
Areas of possible use: archaeology, criminal law, search of underground communications, diagnostics of the state of pipelines, constructions.

In archaeology the use of the developed hardware-software complex allows to solve the tasks connected with the preservation of cultural heritage and purposeful research of historical monuments.

Main technical and operating performances

  • Maximum amount of electrodes - 100 pieces;
  • Effective depth of investigations - up to 4 m;
  • Minimum linear size of the searching object - 0.30-0.40 m;
  • Minimum pitch of change of depth investigations - 0.10 m;
  • Absolute error of restoring objects contour - 0.10 m;
  • Complex power supply - autonomous;
  • Time to set up complex for measurements (no more) - 15 min;
  • Time to conduct measurements (depending on investigations details) - 10-40 min.

Programme system of computing and visualization of measurement results ensures interpretation of resistivity survey data and submits the user the following possibilities:

  • Horizontal section charts of the searching objectmathematical data computing (filtering, interpolation, etc. );
  • determining the parameters of data visualization (visualization range, scale of images, objects boundaries, etc.);
  • constructing the searching objects spatial model;
  • saving the computing results as a graphic file.

Spatial reconstruction of the searching objectThe developed electroprospecting complex, technique and measurements algorithms were successfully approbated within a number of investigations of archaeological remains in Russia (field seasons 1992-1998). Resistivity survey investigations on the territory of archaeological remains enabled to define remains planning and allocate the contours of main archaeological objects on their territory. Measurements technique ensures detailed studying of separate objects, that is, construction of their horizontal section charts (layer-by-layer study of soil objects), vertical sections charts and creating 3D-reconstuction of searching objects.
