Spread Spectrum Induced Polarization(SSIP) Acquisition System

Full-wave Spread Spectrum Induced Polarization System was New generation IP survey system.

It enables large detection depth (>1000 m), high precision 2D and 3D spectral IP measurements.  

On the instrument, with the M sequence pseudo-random spread spectrum signal, which greatly improves the frequency domain resolution and the anti-interference ability of the signal.  

With wireless distributed array receiving system,the spread spectrum IP signal detection achieve  large depth, high efficiency and high accuracy.  

The relative phase spectrum method was used to correct the electromagnetic coupling induction, and the phase response and Cole-Cole model parameters were obtained.  

The signal to noise ratio (SNR) was enhanced by spreading spectrum signal emission, Robust and related techniques.  

Through the precise inversion of multi-frequency points and multiple devices with terrain, Got the precision imaging of the detection target and rich geoelectric information.  

Finally, through the analysis of multi-frequency points and multi-parameter inversion results, we can got the high confidence prediction of metallogenic favorable areas is realized.
