METHOD OF SELECTION linearly polarized SEISMIC WAVES

摘要

1. Method in which the converted three-component geophone medium particle displacement caused by the action of seismic waves to electrical signals, electrical signals from the output of the geophone is determined the current values ​​of the angular positions of the projections of the medium particle displacement vector in the plane rectangular coordinate system and the radial plane by scanning vector electrical signals determine the angular position of the projections of the vector onto each of three planes, and in a radial plane defined yayut unit vector signals, characterized in that therein for selection linearly polarized longitudinal and transverse seismic waves in a three-component accelerometers are used as a seismic sensor signals, convert the magnitude of the accelerometer output signals with a function characterized by a high selectivity to the spatial position of the signal vector that coincides with definable angular coordinates for the selection of certain waves and via scan signals PLANE vector projection five rectangular coordinate system, as well as on the radial plane, wherein the coincidence orientation angles vectors longitudinal or transverse waves with specify their position selection in the chosen coordinate system in the absence of superposition of seismic waves, each wave is represented modulus its corresponding vector of electrical signals, and in the presence of interference seismic waves, each wave is represented part of the module of this vector corresponding to a time slot free by superimposing one wave at each
