Abstract
Способ распознавания сейсмических сигналов, осуществляемый путем сравнения напряжения, сформированного после узкополосной фильтрации, с опорным напряжением, отличающийся тем, что, с целью повышения достоверности распознавания сейсмических сигналов на фоне интенсивных помех от удаленных источников, узкополосную фильтрацию осуществляют в полосе частот, автоматически перестраиваемой в диапазоне высших гармонических составляющих сейсмических сигналов, пропорционально уровню сигнала в полосе частот, соответствующей среднечастотным гармоническим составляющим сейсмических сигналов.The method of recognition of seismic signals, carried out by comparing the voltage generated after narrowband filtering with a reference voltage, characterized in that, in order to increase the reliability of recognition of seismic signals against the background of intense interference from remote sources, narrowband filtering is carried out in a frequency band that is automatically tunable in the range higher harmonic components of seismic signals, proportional to the signal level in the frequency band corresponding to the mid-frequency armonicheskim components of the seismic signals.
