Abstract：In order to enrich detection means and improve the efficiency of electrical method in advanced de -tection.We can obtain the characteristics of front -surrounding rock and to indirectly determine the geolog-ical anomaly by analyzing the percent frequency effect of dual -frequency induced polarization current limiting electric field based on the basic properties of excitation polarization and isotropic electric field repel in rock . The advance detection instrument ’ s emission part adopts isolation rectification regulator and modular design . The transmitted current waveform is obtained by the oscilloscope .The current intensity can be easily adjusted without pole .The design requirements are reached .
