Comparison of geophone (groups of 12) data Geophones and multi-component single sensors (DSU3)

The test results (Figures 11 and 12) indicate that single sensor three component receivers provide better data than conventional groups of geophones in rough terrain. The images from the 3C data have better resolution and better imaging of dipping reflectors. Arguably, the benefits of the 3C data are much more significant than the small increase in random noise that we observe on the single sensor data. The benefits are due to a combination of factors: the smaller (25m) DSU interval compared to the (50m) group interval, the polarization filters, the avoidance of intra-array statics with single sensors, MEMS sensors, and tilt correction.
