| Abstract: | A portable, high-frequency, electromagnetic, P-wave vibrator system was developed. Penetration and resolution can be individually controlled by easy modulation of the sweep signal generated by this electromagnetic vibrator. The tests in some projects indicate that this system has the advantage of high-resolution, steady operation and high efficiency. The feasibility of this system has been tested in shallow engineering-geophysical applications, such as in mined-out area and karst. This will develop the application field in survey. |
