Impact of Time-domain IP Pulse Length on Measured Data and Inverted Models
(2015) Near Surface Geoscience 2015 - 21st European Meeting of Environmental and Engineering Geophysics- Abstract
- The duration of time domain (TD) induced polarization (IP) current injections has significant impact on the acquired IP data as well as on the inversion models, if the standard evaluation procedure is followed. However, it is still possible to retrieve similar inversion models if the waveform of the injected current and the IP response waveform are included in the inversion. The on-time also generally affects the signal-to-noise ratio (SNR) where an increased on-time gives higher SNR for the IP data.
