SEISMIC DEVICE FOR FINDING POSITION OF OBJECTS Russian patent published in 2012 - IPC G01V1/00 G01S15/88 

FIELD: geophysics.

SUBSTANCE: invention can be applied to define the azimuth of the detected objects on the guarded line, compute the number of objects in the group target and classify the detected objects; to perform the above function the objects position finding seismic device uses the spread passive location method with the additional seismic detector; the main information feature for the object targeting is the signals cross correlation function in two channels of signals processing. The value of the signal delay defines the decision on value of the azimuth for the object while the azimuth is corrected by means of the seismic detector; the position finding device comprises three seismic detectors, the first seismic signals processing channel with a time delay line and the second processing channel with a set of time delay lines, correlation devices and an azimuth correction unit; the outlets of the correlation devices connected to the input of the decision-making device and the input of the peak signal range selector, its outlet is connected to the input of the classifier. The input of the azimuth correction device is connected to the outlet of the third seismic detector and its outlet is connected to the input of the decision-making device.

EFFECT: enhancement of accuracy of the definition of objects classification.
