Vector Fidelity of Land Multicomponent Measurements in the Context of the Earth-Sensor System

P01 VECTOR FIDELITY OF LAND MULTICOMPONENT MEASUREMENTS IN THE CONTEXT OF THE EARTH-SENSOR SYSTEM Summary 1 When land multicomponent seismic data are to be used to image converted wave energy or for shear splitting analysis the orientation of the three measurement directions must be known. Further the vector fidelity of these measurements should be high. In this context vector fidelity means that the vector motion of the sensor is correctly resolved along the three orthogonal directions of measurement and that the Earth near the sensor behaves according to a 1-D isotropic model. If either of these assumptions is violated estimates
