SEISMIC DEVICE FOR DETECTION AND CLASSIFICATION OF OBJECTS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: operation of device is based on registration of disturbance of seismic field caused by movement of objects, on oscillation of classification indications within frequency ranges characteristic of determination of classes of objects, on analysis of their quantitative relations and on formation of decision on class of object. Characteristic feature of device lies in insertion into device incorporating seismic converter 1, automatic amplification control 2 and unit 3 for extraction and processing of pulse signals of additional unit 4 realizing operational principles described above. EFFECT: improved capabilities of equipment for classification of objects. 1 dwg
