ADAPTIVE FACILITY TO DETECT AND CLASSIFY SEISMIC SIGNALS Russian patent published in 2003 - IPC

FIELD: identification of remote sources of seismic vibrations. SUBSTANCE: adaptive facility incorporates seismic converter, automatic gain control circuit, pulse signal extraction and processing unit, classifying unit and unit for adaptation to soil parameters varying under effect of meteorological conditions. Adaptation is carried out by means of test action which parameters determine value of correction coefficient for autoregression model utilized in classifier of sources of seismic signals which makes it feasible to raise probability of correct classification of sources of seismic signals. EFFECT: raised probability of correct identification of signals while properties of soil change. 7 dwg
