| Abstract: | For the near-surface FDEM instrument, we review its principle, features, applications and the development trend, particularly the reliability of its applications. We discuss the reliability issue of this instrument in three aspects of the hardware, software, and structure, respectively. We illustrate the new technologies on near-surface FDEM instrument exhaustively, including the progressive embedded technology, simulation technology, parallel processing technology, wireless communication technology and distributed design technology. We point out the improvement of the integrated level, power consumption, precision and processing ability of the system, which represent future research directions of the instrument. With a novel design, the near-surface FDEM instruments by combining effective technologies can be further improved. We expect that this new instrument can observe deeper targets, and has higher resolution than earlier instruments. It will be portable and easy to operate due to its small size, with power consumption comparable to a smart-cell phone. |
