Abstract:

Active electric field detection technology relies on excitation source to actively emit electric field signal, and realizes target detection by measuring potential signal. According to the current research progress of active electric field detection of buried targets, the principle is briefly introduced. And the research status and development trend of the key technology (Marine controlled source electromagnetic) in the field of buried large targets at home and abroad are summarized. Aiming at the problem of active electric field detection of small buried underwater targets, the working mechanism of foreign experiments and advanced equipment is introduced, and domestic research in related fields is summarized, which shows the lack of current domestic research content. Based on the analysis of the research status of underwater electric field sensor at home and abroad, it is pointed out that the existing foundation in the field of active electric field detection of buried underwater targets in China. Finally, the development and application prospect of this technology are prospected.
