METHOD OF DETECTION OF MOVING OBJECTS ON LINE PROTECTED Russian patent published in 2001 - IPC

Abstract RU 2165629 C1

FIELD: protection of sections of terrain and approaches to them. SUBSTANCE: seismic signal is recorded in several preset frequency bands and spectral of recorded seismic signals are determined. Then analysis of high-frequency and low-frequency components of seismic signal spectrum is conducted. Change in relationship of high- frequency and low-frequency components of spectrum is indicative of approach or departure of moving object. EFFECT: enhanced informativeness. 1 dwg
