FIELD: electrical engineering.
SUBSTANCE: method for determining the relative permittivity εR in the soil to be examined for the presence of mines using a search appliance. Search device uses at least one search coil, one transmit and one receive antenna, determine the average signal speed by measuring the transit time of the signal through the air and directly through the ground, then perform similar measurements, shielding the radiation in the direction opposite to the ground.
EFFECT: increased accuracy of determining the relative permittivity of the soil for a more accurate assessment of the depth of the object in the ground.
