FIELD: physics.
SUBSTANCE: method involves emitting a non-directional signal; receiving the signal mixed with noise; matched filtration of the signal; signal detection and indication; the signal is received through the static fan of the beam pattern; the received signal is discretised; the noise level is determined as a result of summation of all readings in the first reception cycle on all spatial channels; the echo signal is automatically detected based on the selected detection threshold successively on all spatial channels of the static fan of the beam pattern and the object is automatically classified after several measurements.
EFFECT: automatic classification of an object.
