A resistivity map was expected to allow the electrical resistivity signal to be imaged in 2D in Moroccan resistivity survey in the mining domain.
A Schlumberger resistivity survey over an area of 50 hectares was carried out to detect resistivity anomalies associated to phosphate disturbances.
To filter out white noise from the resistivity data was used a method based on the auto-regressive model (ARM) approach.
It was implemented by means of AutoSignal routine.
The auto-regressive filtering output of the phosphate deposit disturbances map obtained by this approach shown that ARM gives an effective filtering method which attenuates considerably the noise represented by minor dispersed and random disturbances; it gives a significant reduction of distortion to the shape of the original resistivity signal.
